My problem on Solaris 10 was a bit different. I set the correct $PATH as noted for Solaris earlier in the posts. Each time I tried doing install Bundle::CPAN or the Net::LDAP module I got make: Warning: Ignoring DistributedMake -j option make: Fatal error: No dmake max jobs argument after -j flag /usr/ccs/bin/make -j3 -- NOT OK. I edited the /usr/perl5/5.8.4/lib/CPAN/Config.PM file and changed the 'make_arg' = q[-j3] parameter to 'make_arg' = q[] and now I can install the bundle and any other module directly from the CPAN shell. I am not a programmer, but evidently the version of make that I installed for Solaris could not handle the "number of jobs" flag.
