Please note that glpkmex is a separate project. Probably you should
post your question to the bug tracker of the glpkmex project:
http://sourceforge.net/projects/glpkmex/support
Looking through glpkcc.cpp I found that the status returned is the
original glpk error number plus 100. Thus, in your case the original
error number is 11 (GLP_ENODFS) meaning that the LP problem instance
has no dual feasible solution (only if the LP presolver is used).
