Hey! I feel a little better about my lack of knowledge now -- I think I might
be (slowly) learning!
Because that is exactly what I did.

So here's what I have so far, to see how this is going for a newbie, moving
from hacking makefiles, to hacking portfiles, to actually writing portfiles.
I think I could have picked an easier one than BasiliskII for my first go
'round, but it works, and I'm into the fine tuning now...
compiler options, variants, active variant requirements ...
now I need to figure out how to customize the "make" to "make XYZ".
I'm sure there are many ways this is not right.... there is a lot of
information in the macports website for portfile writing to absorb..

description Opensource 68k Mac emulator.
long_description \
Longstanding 68K Macintosh emulator. You will need an appropriate Macintosh
ROM image and a copy of Mac OS (0.x thru 7.5 for Classic emulation, 7.x or
8.0/8.1 for Mac II emulation). The default "jit" variant enables the
Just-In-Time compiler, which is 32bit only. This may be faster on your system.
It will require the dependent libraries to be built universal. Slirp networking
is also 32bit-only at present. You can try a build without JIT or slirp, and
this will generate a native build for your system (usually 64bit).

# ----------- DEPENDENCIES -------------

#consider how to find out if any other ports already installed are required by
this port
# ----------- AUTOCONF -------------

use_autoconf yes
#this seems to be a funny command -- is there a more elegant way? this is a
custom autogen.sh script

# ----------- COMPILER CHOICE -------------
# a bit complicated
# I confirmed build with clang-3.7 (x86_64 and i386) and gcc-4.0 (can build
i386 only)
# should therefore build with macports apple-gcc40
# confirmed not to build correctly with gcc-42
# clang < 500 means clang 3.3 or earlier
#compiler.whitelist macports-clang-3.7 gcc-4.0 apple-gcc40
#compiler.whitelist {clang > 500} gcc-4.0 apple-gcc40
