Subject: How to patch ruby's gem before an install ?

Hi,

got stuck and cann't find appropriate guide how can I patch gem package
before it gets installed.

For example I'm trying to fix gem for Gosu library:

1. download the gem with "gem fetch gosu"
2. extract contents of the gem with "gem unpack gosu-0.7.45.gem"
3. apply a patch: cd gosu-0.7.45 && patch -p1
/path/to/patch/fix_cflags.patch
4. ??? how to rebuild a gem from modified sources ? I cann't find the
original gemspec.
5. ??? install modified gem with gem install ./gosu-0.7.45.gem

Any idea ?

Thx, David
