the error is caused by the colon in your gem's path. see:

<http://www.gnu.org/software/make/manual/html_node/Error-Messages.html>
<http://www.gnu.org/software/make/manual/html_node/Static-Usage.html>

the question now is, how did the colon get there? can you post the
output of `gem env` for starters?
