drawtk: FTBFS: fonttex.c:24:31: fatal error: freetype/freetype.h: No such file or directory

Imported from Debian bug http://bugs.debian.org/733365:

Source: drawtk
Version: 2.0-2
Severity: serious
Tags: jessie sid
User: <email address hidden>
Usertags: qa-ftbfs-20131226 qa-ftbfs
Justification: FTBFS on amd64

Hi,

During a rebuild of all packages in sid, your package failed to build on
amd64.

On the new 2.5 version the headers are located at
'/usr/include/freetype2/ftglyph.h' instead of
'/usr/include/freetype2/freetype/ftglyph.h' like in previous versions.

Relevant part (hopefully):
> make[2]: Entering directory `/«PKGBUILDDIR»/src'
> CC shapes.lo
> CC create_shape.lo
> CC texmanager.lo
> CC imagetex.lo
> CC fonttex.lo
> fonttex.c:24:31: fatal error: freetype/freetype.h: No such file or directory
> #include <freetype/freetype.h>
> ^
> compilation terminated.
> make[2]: *** [fonttex.lo] Error 1

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
