This is an attempt to rewrite the GNUstep macports ports.
For example, supposing you clone the repository into ~/gnustep-macports-fixes:
cd ~/gnustep-macports-fixes
portindex
Next, edit your macports sources file:
sudo vim /opt/local/etc/macports/sources.conf
and add a line like:
file:///Users/yourusername/gnustep-macports-fixes
