ということでストレージスペースの少ないmacbookairには不向き。
FABMのデベロッパーたちはpythonを推しているらしいので自分もpythonへ移行することに。
以前ブログで話したがmacbookairのターミナル上でpythonを起動してimport PyQt4とするとHomeBrewやMacPortsで二度に渡りPyQt4とPySideをインストールしたにも関わらずエラー文が出てうまくいかなかったがこの原因がわかった。
自分のmacbookairには数種類のpythonがインストールされていた。ターミナルでpythonと売った後にtabを二度打つと：
$ python
python python2.5-config python2.7 pythonw2.5
python-config python2.6 python2.7-config pythonw2.6
python2.5 python2.6-config pythonw pythonw2.7
こんな感じで何種類ものpythonがインストールされてしまっているよう。
そしてもしかしたらPyQt4やPySideといったモジュールはディフォルトのpythonじゃなくて他のバージョンにインストールされているのではないかと考えそれぞれのpythonをターミナルで起動してhelp()→modulesの手順（参照:https://groups.google.com/d/msg/comp.lang.python/TQfB9720m5Q/KIUUrG9wFBsJ）で確認してみるとpython2.7にPyQt4が入っていることがわかった：
$ python2.7

Welcome to Python 2.7! This is the online help utility.
If this is your first time using Python, you should definitely check out
the tutorial on the Internet at http://docs.python.org/2.7/tutorial/.
Enter the name of any module, keyword, or topic to get help on writing
Python programs and using Python modules. To quit this help utility and
return to the interpreter, just type "quit".
To get a list of available modules, keywords, or topics, type "modules",
"keywords", or "topics". Each module also comes with a one-line summary
of what it does; to list the modules whose summaries contain a given word
such as "spam", type "modules spam".
help> modules
Please wait a moment while I gather a list of all available modules...

よしこれでPyQt4そしてnetCDF4も使えるということがわかった。一件落着。
