Anyone built 1.8.7p72 on HP-UX 11.23/IA64 or 11.31/IA64 with pthreads  
enabled? The following works:  
$ gtar zxf ruby-1.8.7-p72.tar.gz  
$ cd ruby-1.8.7-p72  
$ ./configure

But the following does not:  
$ gtar zxf ruby-1.8.7-p72.tar.gz  
$ cd ruby-1.8.7-p72  
$ ./configure --enable-pthread  
…  
$ gmake  
…
