Hi Kacper (and yt-users),

Thanks for your response!  

I should have been more clear and said that I've only been using the yt install script to do everything, and was surprised that libimf.so wasn't compiled.  The full text of my error is:

(yt-x86_64)gpc-f101n084-$ ipython
Traceback (most recent call last):

Best,

P.S. I wrote a meaningless "(though )" in my last e-mail, which was supposed to report that installing ZeroMQ using install_script.bash gives the error

"stream_engine.hpp(97): error #82: storage class is not first
          const static size_t greeting_size = 12"

which I had to manually fix in the source to "static const", and then rerun install_script.bash.
