Hi,

after a full day of trying to build a working Orocos Toolchain from master
on my OSX system I'm very close to giving up.

Here is what I tried:

* Using the system version of Ruby:

(which was 1.8.7) I could succesfully compile the entire toolchain, using
orogen however resulted in not finding the nokogiri gem (it however was
installed using gem install nokogiri).

* Using the Macport version of Ruby:
This is also version 1.8.7, I again could compile the entire toolchain but
got the following error on using typegen/utilrb:

This is actually version 1.9.3 and I got the following error when building
