gcc: error: @PYTHON_CFLAGS@: No such file or directory

[Dan Eble]

I’m using LilyDev 3.  I just ran configure, and now I get this error very 
shortly after I try to compile:

> gcc: error: @PYTHON_CFLAGS@: No such file or directory
> make[1]: *** [out/midi.lo] Error 1

It fails in this way on this commit but not the previous:

On the previous commit, it fails quite a bit later in this way:

> make[1]: *** No rule to make target address@hidden@', needed by 
> `out/NimbusSanL-Regu.otf'.  Stop.

That failure occurs on this commit but not the previous:

Thanks in advance.
