Stas,
That's fine. Although the behaviour has changed as recently as v1.27 where
previously the contents of PERL5LIB were pushed onto @INC rather that
unshifted.
The problem with the current behaviour is that you need a special case when
running under mod_perl. In our set up, we test our scripts as CGIs and with
Apache::Registry and it's nice to be able to set PERL5LIB in one place rather
than two.

We've done something like this, that works in mod_perl and non-mod_perl
environments:
SetEnv PERL5LIB one:two:three:four:three:two:one
Of course we have to explain that with a comment in case someone comes along
in a few months and thinks "I'll clean up that duplication"
We'll probably just apply the patch to our departmental servers and document
that in the build instructions.
Thanks
