Allan, Thanks again for describing that "install_cluster" and "wizard_prep" (and as hinted by you, doubtless further scripts down the road) need to be "hand-held" regarding how to find the custom perl and python modules. Remembering about PERL5LIB should've been obvious. (And thanks for reminding that there should be no quotes around the arg when exporting PERL5LIB - no worries ;). I'll confess that I haven't yet had to explicitly export PYTHONLIB, but I haven't gotten that far yet.
Only, (properly) exporting PERL5LIB still doesn'ty fix things. It's possible I've missed something. You'd think this would (trivially) work and enable all the install scripts and scripts called therein to work. To reiterate, the variable is exported from the shell invoking "install_cluster", with contents determined by "updatedb" and "locate PackageSmart (or PackagePath, or...)", ie., /opt/oscar/lib/ (leaving out the trailing OSCAR/, since this is explicitly included in the scripts). It's easy to test that one is using the right variable contents, by substituting a bogus value and watching it fail, and to test that wizard_prep is inheriting the variable (by having it echo it, say). All seems well here. Only it isn't helping. What might perplex me is that, in /opt/oscar/scripts/wizard_prep, the "use OSCAR::PackagePath;" statement succeeds (and can only succeed when PERL5LIB is set correctly) yet the call of a subroutine (prepare_pool()) in PackageSmart, further down, fails with "Undefined subroutine", and moreover, as if it can't find PackageSmart at all; PackagePath and PackageSmart sit right next to one another in /opt/oscar/lib/OSCAR. I'm obviously missing something. Again, the only thing I can think of comes from what happens if one also puts a "use OSCAR::PackageSmart;" in wizard_prep (which you'd think would be okay); immediate complaints about no "PackMan". PackMan does not exist in my OSCAR tree: [EMAIL PROTECTED] OSCAR]# cd /opt [EMAIL PROTECTED] opt]# find . -name "Pack*" ./oscar/lib/OSCAR/PackageSet.pm ./oscar/lib/OSCAR/PackageSmart.pm ./oscar/lib/OSCAR/PackageBest.pm ./oscar/lib/OSCAR/PackagePath.pm ./oscar/lib/OSCAR/PackageInUn.pm ./oscar/lib/OSCAR/Package.pm [EMAIL PROTECTED] opt]# cd /tftpboot [EMAIL PROTECTED] tftpboot]# !find find . -name "Pack*" ./oscar/oscar-5.1rc1/lib/OSCAR/PackageSet.pm ./oscar/oscar-5.1rc1/lib/OSCAR/PackageSmart.pm ./oscar/oscar-5.1rc1/lib/OSCAR/PackageBest.pm ./oscar/oscar-5.1rc1/lib/OSCAR/PackagePath.pm ./oscar/oscar-5.1rc1/lib/OSCAR/PackageInUn.pm ./oscar/oscar-5.1rc1/lib/OSCAR/Package.pm ./distro/fedora-9-x86_64/PackageKit-0.1.12-10.20080505.fc9.x86_64.rpm ./distro/fedora-9-x86_64/PackageKit-libs-0.1.12-10.20080505.fc9.x86_64.rpm ./distro/fedora-9-x86_64/PackageKit-libs-0.1.12-10.20080505.fc9.i386.rpm Should it? Other than PERL5LIB, was there something else in particular you needed to ensure before wizard_prep could finish and the install GUI (which I have yet to see) fire up? Do you have a quick synopsis handy of just what you had to do to get OSCAR installed on F9? I would be very grateful. In the meantime, I'll triple-check what I'm doing re: your advice. It's encouraging that at least you managed to get this process to work!
