Ok, looks like the MacPorts paths are in there, so that's fine. Actually they're in there three times each, which is unnecessary, so you could edit your ~/.profile or ~/.bash_profile and clean that up if you wanted to. It won't hurt anything to have them there three times, it just looks silly.

Please don't refer to that web site for information about MacPorts. It's inaccurate and not under our control. For more info, please read:

Those instructions say "the file you need is [...] libsvm.jar". The libsvm port doesn't seem to install any jar. It looks like we already have a request in the issue tracker to install this, and a patch to implement that request:

You could try that patch and see if it works for you.
