configure: error: Package requirements were not met

[Dietmar_Schindler at mra.man.de]

Hello!

I tried to build in the modular tree as described at http://wiki.x.org/wiki/ModularDevelopersGuide from the released tarballs using the build script http://webcvs.freedesktop.org/*checkout*/xorg/util/modular/build-from-tarballs.sh and got messages in the process such as


WARNING: xextproto does not exist -- skipping


and finally the error


checking for X11... configure: error: Package requirements (xextproto xtrans xau xcmiscproto bigreqsproto) were not met:

No package 'xextproto' found
No package 'xtrans' found
No package 'xcmiscproto' found
No package 'bigreqsproto' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables X11_CFLAGS
and X11_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.


after which the script exited.

Now there's something I don't understand. I would have thought that if there is a line such as


    build proto xextproto


in the build script, then there has to be a module tar file named xextproto-*.tar.$COMPRESSION in the proto as well as in the everything directory. But there isn't ...
What's wrong here?
