Dear fellow monks

I'm installing perl modules at a customer's web account, where we do not have root access. So I have created a local perl library, "/home/customer/customers_perl_modules".

I install modules with CPAN configured for the local library, and sometimes with perl Makefile.PL PREFIX =/home/customer/customers_perl_modules

The info on the local libray is stored in the myconfig.pm in the .cpan directory in the user's home directory.

Now, all the modules installed do indeed end up inside the "/home/customer/customers_perl_modules"directory, but often not directly under it, but deeper, in directories named after the version of perl that is used, the processor architecture, under the library "site_perl". There is: 

lib/site_perl,
lib/site_perl/5.005/,
lib/site_perl/5.005/i386-linux/

Now, writing 

use lib "/home/customer/customers_perl_modules";

[download]

doesn't work for the below script, I seem to need the two following "use libs" in the script for it to work: 


use lib "/home/customer/customers_perl_modules/lib";          
use lib "/home/customer/customers_perl_modules/lib/site_perl/5.005/i38
+6-linux/"; 
use lib "/home/customer/customers_perl_modules/lib/site_perl/5.005/"; 
use XML::Parser;
use Data::DumpXML;
print "Hi\n";

It seems kind of counter-productive to manually specify the path to each architecture-specific and version-specific directory. I would have thought that this would be handled automatically either by perl itself or by the lib pragma.

So should I:

a) Use some other way than PREFIX and .cpan/myconfig.pm to tell the modules where to be

b) Manually move the modules up and out of the architecture and version-specific libraries

c) use something else than use lib

d) subclass lib module and auto-create appended paths with version, "site_perl" and architecture values added

e) or is my perl broken

? "perl -V" gives this:

Am I missing something?
