You might be using Cygwin, for some strange reason. Instead of OS, he
probably should have said "distribution" (see below).

I concur.

Actually, it does matter. Some distributions ship libraries in two
packages (generally, a libname version and a libname-dev version).
libname-dev includes the header files needed for compiling against the
library. Since many of the distribution's users never compile for
themselves, but rather download prebuilt binaries, they do not need the
headers, and hence do not have libname-dev installed.

For the benefit of those readers who, like myself, noticed that there is
no mentioned of libart in his error message:

According to my distribution's package, the homepage is:

http://www.levien.com/libart/

and the source is located at:

http://ftp.gnome.org/pub/gnome/sources/libart_lgpl/2.3/

What distribution are you using, and is there a good reason for not
using the distribution-provided packages?
