Glad it's working for you!

This is a known issue, though, um... I don't think it's mentioned 
*explicitly* in the docs. The build instructions say to do it in a 
directory different from the source directory, but it doesn't say that 
it doesn't work when building in the source directory.

Anyway it's on our list to eventually fix up the build machinery, though 
it may take some time. Any help is certainly welcome.
