Problem installing antigraingeometry

[Derek Harland]

Hi all

* I have an error when trying to install the antigraingeometry package 
(version:2.5)

   >sudo port -ucv install antigraingeometry
   --->  Configuring antigraingeometry
   aclocal: configure.in: 103: macro `AM_PATH_SDL' not found in library
   Error: Target com.apple.configure returned: shell command "aclocal -I 
/usr/share/aclocal" returned error 1
   Command output: aclocal: configure.in: 103: macro `AM_PATH_SDL' not 
found in library

   Warning: the following items did not execute (for antigraingeometry): 
com.apple.activate com.apple.configure com.apple.build 
com.apple.destroot com.apple.archive com.apple.install
   Error: Status 1 encountered during processing.

* The macro above looks something to do with libsdl, but libsdl is not 
listed as a dependent.  I also have libsdl installed anyway.
* Not really knowing what I'm doing I've tried editing the port file to 
use "aclocal -I /opt/local/share/aclocal" in place of the above (as 
sdl.m4 is in that directory)
* This then has the following errors
Portfile changed since last build; discarding previous state.

* But this may be simply that I have no idea what I'm doing!
