 I put this Portfile together in the hope that the build and install would
 be smooth.  It's not.  It may be that the automatic detection of the
 target architecture is wrong.  The main concern is this:

 *** This configuration is not supported in the following subdirectories:

     (Any other directories should still work fine.)
 }}}

 So what is happening is the build and install is working, but only
 partially.  It would be preferable that the build fails at this point, but
 it does not!

 It looks like the main thing to get right is the target platform
 identifier.  I looked into it briefly, but it's not resolved yet.  I would
 hope that if the target platform is identified correctly (and fully
 supported by gdb 6.8), the port will be functional.

 If anyone has the motivation and patience to look into it further (as I
 will when I get time), the first thing to do is to run port in debug mode,
 i.e.:

 {{{
 sudo port -d destroot gdb
 }}}

 This will provide a lot of information on what port is doing.  The
 destroot target does the configure and build, then runs make install with
 a custom DESTDIR.  MacPorts uses that DESTDIR, called destroot, as a way
 to parse the files in the port, install the files into
 /opt/local/var/macports/software/gdb/ and then activate the port with hard
 links in /opt/local to the files in the software/gdb installation.

 The destroot path for this port is

 {{{
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_devel_gdb/work/destroot
 }}}

 The pitiful truth is that the only files currently installed there are:

 {{{
 .../destroot/
 .../destroot//opt
 .../destroot//opt/local
 .../destroot//opt/local/lib
 .../destroot//opt/local/lib/libiberty.a
 .../destroot//opt/local/share
 .../destroot//opt/local/share/info
 .../destroot//opt/local/share/info/configure.info
 .../destroot//opt/local/share/info/standards.info
 }}}
