What makes you think that? There's no reason to think that a port would use
icu just because it's using pango.

That's odd. If pango was actually exposing icu to clients, it should show up
in 'pkg-config --libs pango' but it doesn't.

It looks like icu is being linked against even though it shouldn't be:
~/src/macports/dports/x11/pango $ nm -m /opt/local/lib/libpangoxft-1.0.dylib |
grep icu
~/src/macports/dports/x11/pango $ otool -L /opt/local/lib/libpangoxft-1.0.dylib
| grep icu
/opt/local/lib/libicule.49.dylib (compatibility version 49.0.0, current
version 49.1.2)
/opt/local/lib/libicuuc.49.dylib (compatibility version 49.0.0, current
version 49.1.2)
/opt/local/lib/libicudata.49.dylib (compatibility version 49.0.0,
current version 49.1.2)
It looks like the issue is glibtool suckage. It landed in libharfbuzz.la which
then made its way into libpangoft2-1.0.la when pango was rebuit and then made
its way into anything that links against pango the next time it was rebuilt
(even though it wasn't actually using it).
Why are we even shipping the .la files. We should really just delete them from
every destroot as they serve no useful purpose and always seem to just screw up
builds.
