Thanks for the quick answer. I'm indeed running into some problems compiling/building IMP. The 1.0 version fails because of some library dependencies I can't solve, but that's not IMP, it's our cluster setup.... The SVN version fails because of a KeyError:
scons: *** [tools/imppy.sh] KeyError : 'kernel'
Traceback (most recent call last):
 File "/home/software/software/scons/scons-2.1.0/..//lib/scons-2.1.0/SCons/Action.py", line 1062, in execute
 File "/home/software/software/IMP/src/scons_tools/imppy.py", line 61, in builder_script_file
  if data.get(env).modules['kernel'].external:
scons: building terminated because of errors.
