MacPorts and mounted file systems

[Dave Horsfall]

I know that MacPorts is not happy with symlinks, but how about a separate 
file system e.g. a mounted /opt?  I ask because there is barely enough 
room on this "new" MacBook Pro (replacing the old one with a dead video 
card) as the SSD is half the size of the original spinning rust, but the 
used Pro was quite cheap.

In other words, does MacPorts use any hard links outside itself?  They will 
fail if the target is on another file system.

Long term plan is to upgrade the SSD when I can afford it.

Thanks.
