Sure.  Here is what I get:

$ cd /opt/local/include/FTGL/
$ grep FTGLTextureFont *
FTGLTextureFont.h:#ifndef     __FTGLTextureFont__
FTGLTextureFont.h:#define     __FTGLTextureFont__
FTGLTextureFont.h: * FTGLTextureFont is a specialisation of the FTFont 
class for handling
FTGLTextureFont.h:class  FTGL_EXPORT FTGLTextureFont : public FTFont
FTGLTextureFont.h:        FTGLTextureFont( const char* fontFilePath);
FTGLTextureFont.h:        FTGLTextureFont( const unsigned char 
*pBufferBytes, size_t bufferSizeInBytes);
FTGLTextureFont.h:        virtual ~FTGLTextureFont();
FTGLTextureFont.h:#endif // __FTGLTextureFont__
