For consistency with the other directions this should be:

make && make install

Looks like the authoritative repo is indeed CVS:

    https://sourceforge.net/p/expat/code/

    $  cvs -d:pserver:anonymous at expat.cvs.sourceforge.net:/cvsroot/expat login 
    CVS password: <RETURN>
    $ cvs -z3 -d:pserver:anonymous at expat.cvs.sourceforge.net:/cvsroot/expat co -P expat
    $ cd expat
    $ ./buildconf.sh
    $ ./configure --prefix=$WLD
    $ make && make install

Looks like it also supports cmake as an alternative.
Also, I forgot how truly atrocious CVS is.

Tarball approach is probably simpler:

    $ wget http://downloads.sourceforge.net/project/expat/expat/2.1.0/expat-2.1.0.tar.gz
    $ tar xzf expat-2.1.0.tar.gz
    $ cd expat-2.1.0
    ... configure and so on as before ...

Out of curiousity, what is it that wayland needs from expat 2.1.0 that
isn't available from 2.0.1?  The UTF-8 fixes, or XML_GetAttributeInfo()?
