First, on the Itanium system they have gcc 3.0 installed, not 3.2. Also, they have Perl 5.005_02 installed which is, what, 7 years old now? Isn't this a new system? In addition, I can't even get Ruby to build on the Itanium system.
On the PA-RISC1.1 system they have gcc 3.2, but with the single thread model, whereas the Itanium system has the posix thread model. Is there a reason for this difference? This system also has Perl 5.005_02. I was able to build Ruby on this machine, but I get mysterious core dumps when I try to add more than 6 members to an rb_struct.
