[wxruby-users] wxruby - compile trouble on 64bit linux (ubuntu)

[Mario Steele]

Actually Alex,

wxRuby's build process won't receive from wx-config, or ruby.h, I had to do
the same hack myself when I did the x86 build of wxRuby gem.  No matter what
I tried, I couldn't get -fPIC in there, and I tried everything.
