Comment (by ryandesign@…):

 You added a comment in your patchfile:

 {{{
 # port echo depends:icu finds dependencies
 }}}

 Note first of all that this finds dependents of icu (i.e. those that have
 a dependency on icu), not dependencies of icu. Second, note that more
 precisely, this finds ports that have dependencies whose names contain the
 string "icu"; this is more than just those that depend on the port icu.
 For example, it would find py-pyicu and gramps (which depend on
 py27-pyicu, not icu) and the webkit-gtk ports (which depend on harfbuzz-
 icu, not icu). Finally, note that this only finds dependencies declared by
 default; it does not find dependencies in non-default variants or that
 vary by platform or other conditionals; for example, if you run the
 command on Mavericks or later, you'll miss sword, which depends on icu,
 but clears its dependencies on Mavericks and later so that it can more
 quickly inform the user of the fact that it is not Mavericks-compatible. I
 usually just grep the portfiles, which doesn't have these shortcomings.

 {{{
 port file all | sort -u | xargs grep -E ':icu( |$)' | cut -d / -f 7 | sort
 -u
 }}}

 However, this produces slightly different output: where "`port echo
 depends:icu`" will print the names of affected subports, this `grep`
 pipeline will print the name of the directory the portfile is in.
