I have installed fenics on MAC OS 10.8.2 but can't run the demos

Run:

  instant-clean

then run your script again and paste the content of the compile.log. In
this case:

/Users/gerardawanou/.instant/error/edb8a2873204f9ff1836a2ea03a9fbc74b6311e1/compile.log

Hi, Gerard, Johan.

Newcomer to Fenics, it happens that I have the exact same error than Gerard.

After following Johan's advice (running instant-clean), I still have the error message on terminal, and the corresponding log (the content of compile.log ) is:

Make Error: CMake was unable to find a build program corresponding to "Unix Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.

Seems like it misses something else related to Cmake installed on my computer? I'll keep digging, but any clue is welcome !
