I figured out why this problem isn't caught by pointyhat. It turns out
that configure looks for libICE and if it finds that, then it assumes
that libSM is also installed and adds both libraries to the linker
command line. Since pointyhat only installs the libraries that are
listed as dependencies and neither of these libraries is a listed
dependency, the configure test for the presence of libICE fail and the
build doesn't try to link to either of these libraries.
When I was rebuilding all of my ports from scratch because I was
upgrading from 7-STABLE to 8-STABLE, libICE must have gotten installed
before startup-notification, which caused configure to want to link both
libSM and libICE. This failed because libSM was not yet installed.
I wonder how many other ports have this bug ...
Here's a patch:
