Here's my guess - you are probably missing some programs necessary to build
the packages. First, make sure you install Xcode from either the Apple
website or the Tiger disc (good time to install X11 if you don't have it
too). Then be sure to check the check box in the apple package gui that
downloads and install dependencies. Try opening terminal and typing 'which
gcc' If it's not there, I believe the above should fix everything! (but
still try the above if it is there...)

best wishes,
Vince
