unsetting the PREFIX setting

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

I was trying to install my own Perl on my shared web host, so I set `PREFIX= ~/usr` when building Perl. However, that process didn't really work very well, so I decided to install Perl using `perlbrew`. I now have Perl 5.16.2 installed, but for some reason the $PREFIX value is still remembered and causes problems. For example, `cpanminus` complains with

Only one of PREFIX or INSTALL_BASE can be given.  Not both.
  MIYAGAWA/App-cpanminus-1.5018.tar.gz
  /home/punkish/perl5/perlbrew/perls/perl-5.16.2/bin/perl Makefile.PL 
+PREFIX=~/home/punkish/perl -- NOT OK
[download]

How do I unset the PREFIX value forever?

I have tried reconfiguring CPAN itself, but I don't know how to set all instances of PREFIX use to essentially whatever the default may be so cpanminus doesn't croak.

When you set it like that, it doesn't persist -- your .profile or .bashrc or a global one (from your admin) is probably setting prefix Also, maybe it is set through sitecustomize, run 'perl -V' to find out `help set help export man set man export` [download]	[reply] [d/l]
