Holy monks,

I am trying to build a few perl rpms on different versions of redhat linux. The spec file contains commands that determine a few directories in /usr/lib/perl5:

perl -V:installvendorlib
perl -V:installvendorarch

I've observed that the above works on some versions only and returns a null string on others. I want to know how these variables are assigned values. Also, is there a simple perl one-liner that returns a list of all such configuration parameters - perhaps as a hash with key and value pairs?

perl's manpage mentions

-V:configvars

and nothing more that that. I also looked in the perlrun manpage but could not find anything useful.

Many thanks!
<Update:

I was looking at the Config module, and figure out I can get all the values I want using

use Config;
foreach (keys %Config) {
  print "$_ => $Config{$_}\n";
}

For some reason, the installvendorlib variable is not defined on one machine. Is there a way to fix this other than recompiling and reinstalling perl ?

Thanks,
Linuxfan
