No need to be hostile.  I do have a build environment set up, but I am completely unable to compile your changes without your source code.  This just sends up a big red flag for me as you've obviously modified the source for some of your builds and are unwilling to provide those changes for peer review.  I think this goes against the spirit of open source.  Modified binary only releases don't help progress the software and create an unnecessary dependency on an individual to provide those binaries.
