in gmsh/configure, there is a directive for designing the location  of 
opencascade.

./configure --with-occ-prefix=/usr/local/opencascade etc...

Open cascade can be downloaded form http://www.opencascade.org/

At this location, you can have pre-compiled versions of occ :

http://www.opencascade.org/getocc/download/loadocc/

Note that we have ported OCC to Apple MAC OSX.

When linking is done, just do

gmsh foo.STEP

gmsh will treat files with extensions ".stp", ".step", ".STP" and 
".STEP" as STEP files.
