I experienced the same problem as Ed when I wanted to upgrade fontconfig
when port reported it as outdated:

fontconfig                     2.4.2_0 < 2.4.2_1


The package would fail to compile:

Error: Target org.macports.build returned: shell command " cd
"/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_por
ts_graphics_fontconfig/work/fontconfig-2.4.2" && make all " returned error 2

I eventually tracked it down to a missing dependency on libxml2:

No package 'libxml-2.0' 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 LIBXML2_CFLAGS
and LIBXML2_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.


I searched for libxml and installed libxml2:

horus:~ root# port install libxml2


After cleaning fontconfig it successfully build again:

horus:/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_graphics_fontconfig/work/fontconfig-2.4.2
root# make clean
