| Subject: | fix @INC search order |
Hello,
Some perl installations have "vendor" installation tree located under
"perl" installation tree, e.g.
$ perl -V
...
@INC:
/usr/lib/perl5/i386-linux
/usr/lib/perl5
...
/usr/lib/perl5/vendor_perl/i386-linux
/usr/lib/perl5/vendor_perl
...
$
Tk::Pod then cannot gork "vendor" tree and simply produces entries
with "vendor_perl::" prefix for these modules. I think the problem
exists with all recent Fedora and Mandriva distros.
Also in some installations some paths in @INC are non-existent out of
the box. The following patch fixes the problem for me:
