I'm new to pyinstaller and have stumbled on the following problem:

[root@localhost pyinstaller]# python Build.py cssh/cssh.spec
checking Analysis
building Analysis because outAnalysis0.toc non existent
running Analysis outAnalysis0.toc
Analyzing: support/_mountzlib.py
Analyzing: support/useUnicode.py
Analyzing: ../cssh.py

     self.fixMissingPythonLib(binaries)
   File "Build.py", line 394, in fixMissingPythonLib
     raise IOError("Python library not found!")
IOError: Python library not found!

Err.. which library is not found?

I have checked in "cssh" dir and there is no txt warnings file in this
spec directory at all. So which library is missing?

Can it be related to this?

Commands I ran (after 'make'ing pyinstaller of course):

# python Makespec.py --onefile ../cssh.py
# python Build.py cssh/cssh.spec
