So I have the less than enjoyable of installing Ruby on a PA-RISC HPUX  
box - HPUX never makes it easy!

I managed to get Ruby 1.8.4 installed from the HPUX ports site, but in  
the installation guide it says they disabled pthreads.

Now when I attempt to install rubygems, its complains about not being  
able to require ‘thread’ as part of its installation.

Does anyone know if there is a way to get Rubygems installed without  
pthread support, or does anyone have a recpie to install Ruby 1.8.4 or  
newer on HPUX with pthreads enabled?

stephen,  
I’ve never tried it on HPUX, but the stock 1.8.6 source  
from [ruby-lang.org](http://ruby-lang.org) compiled on irix 6.5 without any intervention  
(admittedly, it’s got a gnu toolchain installed: autoconf, gnu make  
and gcc 3.x installed). It’s a 32 bit install on a 64 bit box, but  
considering it required no intervention at all, I’m not complaining,  
and I can wait to tweak it.

Having just written that I decided to install gems: it installs fine,  
but complains about the socket library not being there. Humm, guess I  
do need to tweak it.

I have battled with it a long way, and it gets really far into  
compiling before complaining about unresolved symbols around zlib I  
think.

When I build with --enable-pthread it doesn’t get very far at all -  
the build seems to go into some from of infinite loop until it gets  
killed for using too much memory.

Pretty close to giving up on this one - I reckon its going to be  
easier to track down a Linux or Solaris box as I just don’t have the  
HPUX skills to work it out ☹
