Comment (by kencu):

 Here's another hint:
 {{{
 :info:build
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_www_serf1/serf1/work/compwrap/cc/usr/bin/gcc-4.2

 -I/opt/local/include/apr-1 -I/opt/local/include buckets/file_buckets.c
 }}}

 what important thing is missing on these build lines?
