Don't know if this problem is special only to Darwin but I suspect that the include path that is expanded on row 15 in binding.gyp results in string with "-I" at the beginning although the gyp expects the just path.

If I try on commad line

mysql_config --include

I got

-I/usr/local/mysql/include

Anyway, after replacing the contents of the single quotes on that row with just the path to the mysql includes, I was successful to build the db-mysql on OS X 10.6.8. I was also able to successfully build it when I replaced mysql_config --include in the binding.gyp with:

mysql_config --variable=pkgincludedir
