[TriLUG] Perl include path problem

[Jeremy Portzer]

Anyone seen problems with Perl respecting the -I option for include
path?  It appears to work fine with "-V" but then barfs when I actually
try to run a Perl script.

For example, I run this:

bash$ /home/foo/apps/perl/bin/perl -I/home/foo/apps/perl/lib -V
[snippity-snip]
  @INC:
    /home/foo/apps/perl/lib/5.6.1/i686-linux
    /home/foo/apps/perl/lib/5.6.1
    /home/foo/apps/perl/lib
    /usr/local/foo/apps/perl/lib/5.6.1/i686-linux
    /usr/local/foo/apps/perl/lib/5.6.1
    /usr/local/foo/apps/perl/lib/site_perl/5.6.1/i686-linux
    /usr/local/foo/apps/perl/lib/site_perl/5.6.1
    /usr/local/foo/apps/perl/lib/site_perl
    .

bash$ /home/foo/apps/perl/bin/perl -I/home/foo/apps/perl/lib
migration.pl -v
Can't locate strict.pm in @INC (@INC contains:
/usr/local/foo/apps/perl/lib/5.6.1/i686-linux
/usr/local/foo/apps/perl/lib/5.6.1
/usr/local/foo/apps/perl/lib/site_perl/5.6.1/i686-linux
/usr/local/foo/apps/perl/lib/site_perl/5.6.1
/usr/local/foo/apps/perl/lib/site_perl .) at migration.pl line 9.
BEGIN failed--compilation aborted at migration.pl line 9.

====

Obviously, strict.pm is a pretty basic Perl module, so the script is
getting nowhere (/usr/local/foo doesn't actually exist)

This is a specialized version of Perl, which has apparently been
precompiled to include "/usr/local/foo/apps/perl" as its default root. 
But I need to point it at /home/<blah> instead.  The -I option appears
to do that, adding it to @INC when I run perl -V.  But yet when I run
the actual script, the @INC no longer has the /home/<blah> path
included.  What the heck?

No, I can't make a symlink from /usr/local/foo to /home/foo, though that
would solve the problem.  (The reason for this is irrelevant to this
question, so I'll leave it out for brevity.  The -I option *should*
work!)

Thanks for any ideas!
