It should have still installed it.  Maybe pkg-config just can't find it.
What architecture are you running?  If it's an AMD64, I've seen an
issue where some of the libraries installed by jhbuild get installed
in ${prefix}/lib and some get installed in ${prefix}/lib64.  When they
get installed in the 'wrong' one, pkg-config can't find them. I
haven't figured out yet exactly why that is, but you might check that
if you're using an AMD64 system.  If that's the case, you could add
the other one to PKG_CONFIG_PATH (or whatever it's called) or just use
a symbolic link the cairomm-1.0.pc file to a directory in pkg-config's
path.

You need to have libpng installed in order for png support in cairo. 
It might be enough just to install the libpng-dev packages from your
distro, or you might need to install them from source to the same
prefix you're installing cairo with jhbuild (e.g. /opt/gnome2 or
similar).  Then you'll need to rebuild cairo.
