        <pre>I'm trying to build 2.10.3 on a slackware box under the old garnome build system (I've being doing this for years).  
The build dies as shown in the log below. Pixman exists on my machine and without an nonstandard environment values
seems to be found; i.e.,

pkg-config --modversion pixman-1
0.33.1

echo $PKG_CONFIG_PATH
/usr/local/lib64/pkgconfig:/usr/local/lib/pkgconfig:/usr/lib64/pkgconfig:/usr/lib/pkgconfig:/usr/share/pkgconfig

Here's the full log:

[ 97%] Generating ../../WebKit2-4.0.gir
Package pixman-1 was not found in the pkg-config search path.
Perhaps you should add the directory containing `pixman-1.pc'
to the PKG_CONFIG_PATH environment variable
Package 'pixman-1', required by 'cairo', not found
