 kind of explained here:

 https://gist.github.com/raw/933741/93ded0007937f70df19aeb3d77f523a9dbd5639c/gistfile1.txt

 What happened is I did a $ sudo port install mplayer
 one day.  I think I did a control+c to cancel it sometime in the middle.
 Next day, I did
 $ sudo port install mplayer
 again.

 m4 is a dependency of mplayer.
 With the first one, the m4 install was interrupted.
 Now, however, you can see from the gist that it was saying
 ":debug:main Skipping completed org.macports.fetch (m4)"

 then attempting to build from:

 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_devel_m4/work/m4-1.4.16

 $ ls
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_devel_m4/work/
 .CC_PRINT_OPTIONS   .macports.m4.state  m4-1.4.15/

 So basically it appears to be skipping the fetch phase because 1.4.15 had
 already been fetched (and unpacked), then trying to go ahead and build
 1.4.16, which of course fails.
 Less than ideal, wouldn't you agree?

 10.6.7, xcode 3.2.6
 Thanks.
