Thanks for the report; this is fixed now in the git repository, please test.

Thanks for you thoughts, to which I basically agree.  I will discuss this issue on the freetype-devel mailing list after the next FreeType release.

On second thought, the old behavior with a freetype/ dir would be more convenient.

With the current set-up;
pkg-config --cflags freetype2
-I/opt/local/include/freetype2 -I/opt/local/include -I/opt/local/include/libpng16

over 40 files with short names -- and short prefixes, ft or tt -- are added to the compiler's search path. If all libraries would do that, projects with more than just a few libraries become a compilation nightmare. In version 2.5.0 (don't know where the exact change was), most of these files were still under a directory freetype/

I currently have a problem compiling projects with FTGL on Mac OS X, which uses freetype.

FTGL has a header FTGlyph.h, and freetype has a header ftglyph.h. Mac OS X is by default (as is Windows always) not case sensitive in header includes, so these files now clash.

There used to be no problem, because the freetype headers were one level deeper, and the config/ftheader.h file (at least in 2.5.0) had lines like:

#define FT_GLYPH_H  <freetype/ftglyph.h>

the current 2.5.5 freetype (just a minor update), removed the freetype dir, and now:

#define FT_GLYPH_H  <ftglyph.h>

This requires a compile flag that includes the freetype header directory (e.g. -I/usr/include/freetype2). That effectively amounts to dumping the freetype headers in the total pool of headers, which I personally think is bad form.

It would be (much) better to include the directory prefix in the defines, to reduce the possibility of header name clashes, so:

#define FT_GLYPH_H  <freetype2/ftglyph.h>
