Gem install displays 'PostInstall.txt' instead of contents

[samueldana]

I'm guessing this isn't intended behavior, but when I install my gem, 'PostInstall.txt' is displayed instead of its contents.
Example: when i do 'gem install newgem' I get:

PostInstall.txt
Successfully installed newgem-1.5.3
1 gem installed
Installing ri documentation for newgem-1.5.3...
Installing RDoc documentation for newgem-1.5.3...

My system is OS X Snow Leopard running Ruby 1.9.1 p378
