How do I install Postscript Fonts (.pfb) in OS X

Howdy,

I'm a recent switcher from Vista to OS X, and I cannot for the life of me get any of my .pfb PostScript fonts to work on OS X? Its suppose to have built in support for it Like Windows but I am either doing something wrong or that was a lie!

All I have unfortuntely is the .pfb and .pfm files for my PostScript fonts.. do I need any other files? The pfb's on their own worked in Vista, so I'm just assuming that it should be the same for OS X right? I tried imported the fonts via the Font Book but I cannot select .pfb files, so I tried dragging the pfb and pfm files into Library/Fonts and still to no avail?

Any ideas on how I can get these fonts to work? or am I screwed?
