Hello everybody !!!
Michael Walter reported a bug that could happen with the current CBC
package. This spkg used to contain several files to enable the use of the
CPLEX solver in old versions of Sage, stuff which had remained there so
that the package would stay compatible with those old versions of Sage.
It has been a while, though.
It has been a while, and besides, this stuff actually created problems
when somebody installed cplex before cbc : the cbc spkg tried to compile
the CPLEX stuff even on new versions of Sage, and Sage actually did not
like that `:-)`
The new spkg is available there, and the problem mentionned above is
actually solved by removing some files and several lines in the former
spkg-install.
While I was at it, I updated the source from 2.3 to 2.7.5, which is worth
doing already.
Here it is :

(there is also a small patch removing a few characters from
module_list.py)
