[maemo-developers] Cross-compiling Ruby 1.9.2

[From: max]

I am attempting to cross-compile Ruby 1.9.2 for ARM using Scratchbox
(am new to cross-compiling). However, ./configure throws an error
saying
 "checking whether setpgrp takes no argument... configure: error:
cannot check setpgrp when cross compiling".

If it won't lead to much issues, can I disable the check?

All help appreciated. I would very much love to have Ruby 1.9 running
on my N900. :)

P.S: I am using the Maemo 5 SDK to build ruby-1.9.2-p180.tar.gz in
scratchbox, and I am using the following command to run configure:
./configure --host=i486
