The OsiGlpk interface seems to be out of date and does not work properly 
with the current version of GLPK. However, it should work with GLPK 
versions earlier than 4.4. We have tried this with SYMPHONY and it seems 
to be OK. Let me know if you have problems with it. In the menatime, we 
will work on getting the OsiGlpk interace up to date.

Could you be more specific? The only mention I find of GLPK in the FAQ's 
is where it states that there is an OSI interface for GLPK.
