Dear Monks

I'm trying to install a second (local) perl, because for some unknown reason, the current perl on my Mac doesn't work very well (e.g. cannot run cpan) So I downloaded 5.10.0 and executed the following commands

$> sh Configure -de -Dprefix=/Users/jeanluca/software/perl
..... 
$> make
.....
$> make install
.....
./perl installperl --destdir=  
/usr/local/bin is not writable by you
make[1]: *** [install.perl] Error 2
make: *** [install] Error 2
[download]

I tried to solve this as follows

$> ./perl installperl --destdir=/Users/jeanluca/software/perl
[download]

but I get the feeling this is not the right solution:

$> export PERL5LIB=/Users/jeanluca/software/perl/usr/local/lib/perl5/5
+.10.0/
$> /Users/jeanluca/software/perl/usr/local/bin/cpan
-bash: /Users/jeanluca/software/perl/usr/local/bin/cpan: /usr/local/bi
+n/perl: bad interpreter: No such file or directory
[download]

How do I tell the installation procedure where to put the executables, because I want to have everything local!

Cheers

UPDATE: The solution was easier then I thought: remove config.sh
After executing the configure command, this file is created. When executing it again, configure uses the config.sh for its default values. Apparently the first time I executed the configure command I did

$> sh Configure -de
[download]

And finally, as stated by jnbek, the default values overwrite the command-line arguments!
