Occasionally I visit Ohloh.net to satisfy my stats addiction.

One of the things Ohloh analyses in the source code is license information[1]. On the Ohloh MediaWiki page[2] an analysis summary is displayed. It contains the following warnings (number of files added by me from [1]):

# Mozilla Public License 1.0 may conflict with GPL (253 files) # PHP License may conflict with GPL (7 files) # Apache Software License may conflict with GPL (1 file) # Artistic License may conflict with GPL (7 files) # Common Development and Distribution License may conflict with GPL (1 file) # Apache License 2.0 may conflict with GPL (7 files)

I am wondering if any of these warnings can really point out a licensing issue. If they do, I think we need to persue this, and get it sorted out.

Anyone who can shed some light on this?

Cheers! Siebrand
