Yes and no:

Yes: it doesn’t take much effort to set up a local tree.

No: you are now responsible for keeping the port up to date yourself, as 
automatic updates are not applied to local Portfiles.

As far as comparing Fink vs. Homebrew vs. MacPorts, I could have benchmarked 
that until about a year and a half ago. Before I updated my cluster to Yosemite 
and installed MacPorts on all of the machines, I had all three installed on 
identical machines (Mac Pro Nehalem). However, there are also differences 
within each platform, depending in the variant built. For example on my work 
office machine I have octave @4.0.0_1+atlas+gcc49+glgui+gui+metis+qtgui. 
Building w/o atlas or Metis/SuiteSparse will make a lot of difference in terms 
of performance. Using different versions of gcc also may make a difference (not 
tested, I have built octave 4.0.0 with gcc-4.8, gcc-4.9 and gcc-5).
