I have spent some time debugging an issue in a (vanilla ObjC) iOS app, where I got that same error message ("Not a directory").

A hint that might reduce debugging pain: fopen will fail with ENOTDIR when "a component of the path prefix is not a directory." You would, for instance, get the ENOTDIR error if you would try to open /dev/null/a

I went ahead and just recompiled the lib with '--enable-debug' first (which I'll keep enabled till end of beta)

I've decided to remove '--enable-debug' for regular testing due to the massive decrease in rendering performance (but will re-enable whenever I see a possible issue).  I also get hundreds of errors on startup with it enabled - whenever gambit needs to do a ##include or 'load' - though everything still works fine.  It seems to be treating files as a directory somewhere and then recovering.  Here's a sample:

Is that normal?  Thanks,
