---------------------------+--------------------------------
 Like 189 of portpkg.tcl uses the findBinary procedure to locate the full
 path to the cpio binary and then uses that as the value to the -x
 parameter of the pax command.  This causes pax to segmentation fault.

 The command that fails is:

 cd
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports
 .org_release_tarballs_ports_multimedia_mythtv-core.25/mythtv-
 core.25/work/destroot && /bin/pax -x /usr/bin/cpio -w -z . >
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports
 .org_release_tarballs_ports_multimedia_mythtv-core.25/mythtv-core.25/work
 /mythtv-core.25-0.25.2-Fixes-20120918.pkg/Contents/Archive.pax.gz

 The attached patch file simply uses 'cpio' as the parameter to -x option
 of pax rather than the calculated full path (ie /usr/bin/pax).  With just
 'cpio' there is no segmentation fault.
