I guess this is the same issue as disscussed here
https://stackoverflow.com/questions/9834776/java-nio-file-path-issue

When loanding sovers libraries, I receive an error "Unable to load library ....". The error include a path that looks like to be wrong "darwin/liblibglpk.dylib", it seems to miss one "/" between the two ...liblib.....
The options xxxSolverLibraryName do not work when introduce the default path for libraries.
