Rosetta 3.3 Compilation error

Hello. I am quite new to Rosetta, Cygwin, Scons. I am currently running Windows 7 64-bit. I so far have installed MinGW, cygwin, python 2.7.2 and scons.

Here is the message I get from cygwin:

$ scons.bat bin mode=release
scons: Reading SConscript files …

KeyError: “Unknown version number 8.0 for compiler ‘gcc'”
scons: done reading SConscript files.
scons: Building targets …
scons: `bin’ is up to date.
scons: done building targets.

I had to add the Python27/scripts/ to the $PATH in order to get scons to work.

Any inputs are appreciated.
