[gentoo-user] perl 5.8.6 install/update - @INC not working, solved?

[michael higgins <gentoo.lists@snet.net>]

Hello list.

I just decided to rebuild perl as I recently noticed that perl wasn't working for me anymore. When I just happened to need to use it, of course.

As an aside, if perhaps relevant, I had a couple of problems with failed compiles. As is usually is the fix for this machine, I opened the case, and the compile finished. New perl installed, no big deal. 

And then an emerge message indicated I should complete the update via perl-cleaner. Ran perl-cleaner.

However, still, trying to run even perl -V yields:

Can't locate Config.pm in @INC (@INC contains: /etc/perl /usr/lib/perl5/site_perl/5.8.5/i686-linux /usr/lib/perl5/site_perl/5.8.5 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.5/i686-linux /usr/lib/perl5/vendor_perl/5.8.5 /usr/lib/perl5/vendor_perl /usr/lib/perl5/5.8.5/i686-linux /usr/lib/perl5/5.8.5 /usr/local/lib/site_perl .).
BEGIN failed--compilation aborted.

. . .

I finally noticed that the @INC doesn't include the new perl folder for 5.8.6. Ah.

Looking into it, it would seem that 'which perl' gives /usr/local/bin/perl. This is, apparently, not a link. It is, however the perl that is broken... but 

ls -l /usr/bin/perl
lrwxrwxrwx  1 root root 9 Jul 13 16:46 /usr/bin/perl -> perl5.8.6

and 

/usr/bin/perl -V

Does work... as expected. So, what happened? And, how do I fix it?

 # cd /usr/local/bin
 bin # mv perl perl5.8.5

Okay. That wasn't so good. I got a failed reference to /usr/local/bin/perl from bash, so I tried:

# cp /usr/bin/perl /usr/local/bin/perl

And that seems to work. But, my question is, still, why was there another perl in /usr/local/bin... Could be it got promoted in my path somehow? 

And why would bash still look for /usr/local/bin/perl when I run a script, when /usr/bin has a perl that is working (and is the one that's #!referenced at the top of my script anyway)?

TIA for any enlightenment in this area. '-)
