I'm assuming your commercial App isn't GPLed and that your module is a
library against which your commercial app is linked. Assuming my
assumptions are true, you are indeed violating GPL if you are planning
to link your non-GPLed app against a GPLed library. You either have to
GPL your commercial APP[1] or find an alternative module that is not
GPLed (preferably BSD or LGPLed).
Had this library been LGPLed and you made modifications to it, you
will still have the freedom of releasing only the modified version of
the library alone (not the oftware that links against your library).
Also, looking at it from the community perspective, The Free Software
Movement recommends programmers to release their libraries under GPL
and not LGPL. The readline[2] story is a pretty interesting thing to
read. But looking at it from the bread and butter perspective, its a
different thing altogether :)
