Hmmmm ... /usr/local/lib/ruby/1.8/pstore.rb?? Where is your Ruby 
*interpreter* stored? Did you install it from a 64-bit-compatible RHEL 4 
RPM or some other way?

I think the problem is the Ruby interpreter, not any of the packages. 
The segfault appears to have happened when the interpreter was on line 
354 of "pstore.rb" as noted above. Make sure all your packages are pure 
64-bit and installed from reputable RPMs, or rebuild them from source 
RPMs with "rpmbuild".
