Anything that builds using the standard CPAN method, ``perl Makefile.PL;
Make, ...'' will take care of that automatically. For other scripts I
generally use something to the effect:
%build
...
find . -type f | \
xargs egrep -l '/usr/bin/perl|/usr/local/bin/perl' > tmplist
%{l_shtool} subst -s \
-e 's!/usr/bin/perl!%{l_prefix}/bin/perl!g' \
-e 's!/usr/local/bin/perl!%{l_prefix}/bin/perl!g' \
`cat tmplist`
One could even do something similar to change all references to
``/usr/local'' to ``%{l_prefix}''.

In many cases this requirement is a CWA note, usually meaning that the
project depends on perl modules that are included in the RH or other
distributions.
While it may take some effort to adapt packages like this to run under
OpenPKG, IHMO it's well worth it. I've been developing and maintaining
various *nix based systems since 1982, using quite a bit of open source
software to provide a uniform base across all systems. Until I started
using OpenPKG after reading Ralf's article in SysAdmin, I spent a lot of
time dealing with vendor specific issues, and my modifications would almost
always render the vendor's on-line updates useless as I had to hack their
RPMs (I used Caldera Linux from 1994 until SCO started suing everybody in
sight :-). Having a uniform packaging system, independent of the vendor's
has made my life far easier, and I don't have to worry about breaking the
vendor's stuff (you ever looked at the guts of a Cobalt RAQ system :-).
