Hi Gilles,

Good to hear you got it working.  I have opened a bug in Trac, #360:

http://www.mlpack.org/trac/ticket/360

If you are interested in helping resolve the issue with mlpack_test, you
can try some of the things I've suggested there, but either way, you
have something working, so if you don't have time to look into it, I'll
look into it eventually...

Thanks,

Ryan
