in principle yes, although libfontconfig.so.1.4.3 (from 2.7.3) and
libfontconfig.so.1.4.4 (from 2.8.0) both use the same soname and thus ought
to be compatible.
I could try to build (actually already done) and install fontconfig-2.8.0,
but should then first upgrade freetype-2.3.11 => freetype-2.3.12 or maybe
even to freetype-2.4.1.
Moreover there are zlib-1.2.3/1.2.4/1.2.5!
Which versions are used by Ubuntu 10.4?

Reinhard has answered this.

Could this different behaviour be due to different gcc (and glibc?)
versions -- caused in both cases by some obscure bug?
