Actually, the FSF / GPL folks disagree--
from the horses mouth:
A consequence is that if you choose to use GPL'd Perl modules or Java classes in your program, you must release the program in a GPL-compatible way, regardless of the license used in the Perl or Java interpreter that the combined Perl or Java program will run on.
( From the GPL FAQ
Many people disagree with the FSF interpretation, however from a commercial standpoint, without specific exception from the copyright holder, I've got to be concerned with the above. In house, I can use LGPL, BSD, Apache, and many others, but cannot use anything tainted with the GPL.
