Dear colleagues,

After installing Cygwin succesfully, I have even compiled Maxima and
it's working fine (except XMaxima isn't working, but this is not
supported software anyway), I tried to compile Code Aster, a nice FEA
package from EDF, making the corrections suggested in the Code Aster
user group about blocking multithreading testing, and the setup.py
scritpt ended with this error message:

"""

I thought it was something related to the change I did, but when
trying to invoke IDLE, some time after that, a very similar message
came out:

All the refered libraries are in place, with usual permissions.

Has anyone of you ever run run into something like this?

I thank you very much in advance for any hint.
