No FTGL, says configure script?

[Jordi Gutiérrez Hermoso]

This is a little odd. I think it might be a bug in the configure script?

I see at the end,

    configure: WARNING: "FTGL headers not found. Native renderer will
    not have on-screen text"

And further up, I see,

    checking FTGL/ftgl.h usability... no
    checking FTGL/ftgl.h presence... no
    checking for FTGL/ftgl.h... no
    checking FTGL/FTGL.h usability... no
    checking FTGL/FTGL.h presence... no
    checking for FTGL/FTGL.h... no
    checking FTGL.h usability... no
    checking FTGL.h presence... no
    checking for FTGL.h... no
    checking for FTGL/FTGL.h... (cached) no
    checking for FTGL.h... (cached) no
    configure: WARNING: "FTGL headers not found. Native renderer will
    not have on-screen text"

(full output of configure as well as config.log attached).

However,

    address@hidden:~$ ll /usr/include/FTGL/ftgl.h
    -rw-r--r-- 1 root root 4.2K 2008-06-16 09:38 /usr/include/FTGL/ftgl.h

What's going on? Is this part of the reason why the native GL graphics
of Octave don't have FreeType fonts, or a bug in configure.in? Or
something else?

Thanks,
