Currently the GVMT has only been tested on the x86-linux platform, but it should work on any posix-compliant x86 platform. GVMT can be installed in the following steps:

1. Download GVMT from http://gvmt.sourceforge.net/
2. Unpack into a clean directory, $(GVMT)
3. Download the lcc c compiler from http://www.cs.princeton.edu/software/lcc/
4. Unpack lcc into $(GVMT)/lcc
5. Install llvm (version2.5) from http://llvm.org/releases/download.html#2.5
6. Type make
7. Type sudo make install (You will need write privileges to /usr/local in order to install the tools)

If it doesn't work, then email me.
