Currently I am working on MacbookPro Retina installed with OS X 10.10.
I have a VMware virtual machine on my USB 3 hard drive, which I can

However for correctness and performance testing, which option is the best?

* compile the gegl directly on OS X (which I can't get it compiled)
* compile on a Linux VM that runs on VMware Fusion 7.1
* install Linux on my USB hard drive, boot my retina macbook from the
Linux USB hard drive and compile from there?

Test something that typical users use. That would be a plain OSX or Linux install. USB harddrive will make boot, application startup a bit slow but should not impact perfomance otherwise. And as long as your compare performance on the same system, comparisons will stay valid.

GEGL should compile on Mac OSX. If it does not, it is probably not so hard to fix. And it needs to be fixed for applications using GEGL (like GIMP) anyways.
Post your compile error along with what you did here if you are stuck with a problem.
