Thank you very much for the info.

As I said, I was not really worried for myself, but rather for our 
users. Let me try to explain.

In our software project (the Parma Polyhedra Library, we use glpk in a demo application, mainly 
for debugging purposes: we have developed an exact arithmetic mip solver 
and we want to check if the results we are obtaining agree with those 
obtained using glpk. It is acceptable that the user hasn't installed 
glpk at all, or that an old version is found. Hence, it is not really 
appropriate to have our project depend on glpk. Rather, at configure 
time, we try to detect the installed version of glpk and, based on that, 
we conditionally enable/disable the various tests.
With the valuable info you provided we should be able to write 
meaningful auto-configuration code.

All the best,
Enea Zaffanella.
