That makes sense. I'll get the dependents revisions updated, and for
future releases see about patch libevent to embed the version
information into the library. Apologies for the confusion.

Brett,
This is a dynamic library, the issue is that libevent renames
the .dylib on each version upgrade. Maybe they change the ABI so
this is a way to force dependents to recompile? I don't know off
hand.
The current shared library is named
/Users/blair/my-macports/lib/libevent-1.4.2.dylib
and binaries that use it end up with this name in the binary:
$ otool -L /opt/local/bin/memcached
/opt/local/bin/memcached:
/opt/local/lib/libevent-1.4.2.dylib (compatibility version
3.0.0, current version 3.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0,
current version 88.3.10)
So an upgrade to libevent 1.4.3 presumably will remove that
libevent-1.4.2.dylib file.
I don't see how MacPorts should handle this problem gracefully.
Agreed that it is a pain to update all dependents. Presumably a
simple recursive grep should be enough to find them all.

Blair

Blair,
Thanks.
I presumed that depends_lib would track versions for static
libraries, to maintain state. I was also unaware that dylibs are
broken compared to normal shared libraries, live and learn.
Noted, and I'll track down the rest of the dependencies. Bumping
revisions manually in all dependent ports (possibly maintained by
separate authors) seems broken.

Brett,
When you bump a libevent version, please bump the revision number
on all packages that depend upon it since they will need to be
recompiled.
Here's memcached after running with the libevent upgrade:
$ /opt/local/bin/memcached --help
dyld: Library not loaded: /Users/blair/my-macports/lib/
libevent-1.3e.1.dylib
Referenced from: /opt/local/bin/memcached
Reason: image not found
Trace/BPT trap
I've bumped the revision number of memcached in r36063 to force a
recompile.
