I'm attempting to build perl+a number of cpan modules into a single package for distribution. Here are the the caveats: I can't use relocatableinc because useshrplib is a requirement and it runs on an automated build server where many jobs expect perl to live under /opt/perl, but I'm rebuilding a replacement that will go under /opt/perl but can't build there because of the other jobs expecting /opt/perl to exist.
I've tried configuring with prefix=/opt/perl and installprefix=/tmp/perl (also prefix=/opt/perl and make install DESTDIR=/tmp/perl) but when I go to install modules after a make install, the build under /tmp/perl is attempting to use various libs from /opt/perl. I've tried modifying CPAN::Config.pm's makepl_arg to use a PREFIX under /tmp/perl, but no dice.
Is there any nice way to do this? Chroot?
