Comment (by mascguy):

 Attached timing info, as well as a process sample of the MacPorts tclsh
 process. The file registration process for `texlive-fonts-extra` took a
 little over 28 minutes, and total port installation time was approximately
 30 seconds.

 If you review the timing file (`port-install-texlive-fonts-extra-
 timings.txt`), you'll see the performance is very non-linear: It's
 extremely fast at first, but growing progressively slower. By the end of
 the process, only a few hundred file registrations are occurring during
 every 15-second interval.

 As for profiling, I started by adding `package require Tclx` at the top of
 `portinstall.tcl`, but that resulted in the following error:

 {{{
 DEBUG: unknown user id:
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports
 .org_macports_release_tarballs_ports_texlive-fonts-extra/texlive-fonts-
 extra
 }}}

 Is the profiler in the TclX package, the one to go with? If so, any ideas?
