PREFIX_PATH broken w/ jruby-1.6.4

Installed with:

The dir is emtpy:

Looks like it's installing it into the ~/.rbenv/versions dir itself :-(

The same thing happens with 1.9.2-p290. ./rbenv/versions1.9.2-p290 is empty and .rbenv/versions contains bin, include, lib and share directories.

versions :: (master*) » ls -l                                                                              ~/.rbenv/versions

The offender is https://github.com/sstephenson/ruby-build/blob/master/bin/ruby-build#L9

➜ ~ type -p greadlink readlink| head -n 1
greadlink not found

Actually, I'm using zsh. If I use the bash shell (which the script uses) it works fine.

I've confirmed that this commit broke it 20f7b5c

Thanks all, and sorry for not properly testing the $PREFIX_PATH change. I've reverted it and tagged v20110906.1.
