trouble installing minifi

[mjruddell]

I've been following the instructions for installing minifi, and everything 
worked up until i ran the 'make' command from the build folder. Partway through 
the make process, I get the following errors (see below). Has anyone seen this 
before, and what can I do to fix it?

Thanks in advance for your help..
