Hi,  
When trying to compile ruby-frontbase version 1.0.1 on a G5 PPC  
machine, I get this:

# gem install ruby-frontbase

Building native extensions. This could take a while…  
ERROR: While executing gem … (Gem::Installer::ExtensionBuildError)

Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/ruby-  
frontbase-1.0.1 for inspection.  
Results logged to /Library/Ruby/Gems/1.8/gems/ruby-frontbase-1.0.1/  
gem\_make.out

Does anyone a) how to fix this and/or b) whom I should contact about  
getting the gem to work under Leopard?

Thanks.

In case anyone’s interested, here’s how I got it to install:

1. Download the gem source (ruby-frontbase-src-1.0.1.tgz) from  
[http://rubyforge.org](http://rubyforge.org)  
([http://rubyforge.org/frs/?group\_id=1635&release\_id=5201](http://rubyforge.org/frs/?group_id=1635&release_id=5201)).

2. Do the following:

tar xzf ruby-frontbase-src-1.0.1.tgz

cd ruby-frontbase

\<edit frontbase.c so that lines 23-63 are commented out\>

gem build ruby-frontbase.gemspec

sudo gem install ruby-frontbase
