Installation problem - XML::LibXML on snow leopard with ActivePerl

rovingeyes has asked for the wisdom of the Perl Monks concerning the following question:

In Mac OS X (snow leopard) have libxml2 installed in /usr/local and I'm trying to install XML::LibXML, but for some reason the Makefile can't find it. I need some help. Here is the output when I run Makefile.PL.

perl Makefile.PL LIBS='-L/usr/local/lib -lxml2 -lz -lpthread -liconv -
+lm' INC='-I/usr/local/include/libxml2'
Set up build environment without MacOSX10.4u SDK (will build native bi
+naries)
enable native perl UTF8
looking for -lxml2... no
looking for -llibxml2... no
libxml2 not found
Try setting LIBS and INC values on the command line
Or get libxml2 from 
  http://xmlsoft.org/
If you install via RPMs, make sure you also install the -devel
RPMs, as this is where the headers (.h files) are.

So I ran with DEBUG turned on & here is what I see:

perl Makefile.PL LIBS='-L/usr/local/lib -lxml2 -lz -lpthread -liconv -
+lm' INC='-I/usr/local/include/libxml2' DEBUG=1

Any idea what I'm doing wrong?

Try 'perl Makefile.PL XMLPREFIX=/usr/local'. With that, it should be able to run xml2-config to figure out the rest.	[reply]

Looks like this time around, it is actually finding & using xml-config but still no dice: perl Makefile.PL XMLPREFIX='/usr/local' Set up build environment without MacOSX10.4u SDK (will build native bi +naries) enable native perl UTF8 running xml2-config...untested Note: libxml2 2.7.8 was not tested with this XML::LibXML version. looking for -lxml2... no looking for -llibxml2... no libxml2 not found Try setting LIBS and INC values on the command line Or get libxml2 from http://xmlsoft.org/ If you install via RPMs, make sure you also install the -devel RPMs, as this is where the headers (.h files) are.

The debug output above shows another problem: "ld: warning: in /usr/local/lib/libiconv.dylib, missing required architecture x86_64 in file" Looks like libiconv was built as 32-bit only - you'll need to fix that to use it from a 64-bit Perl.	[reply]

I am encountering this problem, albeit under slightly different conditions. And this solution just feels cumbersome... Is it indeed the case that, if you are encountering a lib-path problem in the installation of this package, that you must (I think...) `look` at the package in `cpan` and then type this command? Instead of simply being able to `install` it? Is there (not?) a way to specify the library search path, by means of some `cpan`-configuration entry or another? It’s all just so wonderfully automatic, so much of the time ... isn’t there a cleaner and therefore better way to do this? (See also: http://www.perlmonks.org/?node_id=847888. I am by no means the first person across many years to have encountered or discussed this; this I know. I’m not saying that anything about it is per se “wrong,” only that it feels like driving around on a square wheel.) Note that on the target system a compatible version of the underlying library is installed, just not in a place where the CPAN installer script can find it. Is there a “really good” way to specify this kind of environment-related info?
