After you have finished building the basic things from ThirdParty
required for SOPE, you can go on building SOPE itself.
As always, please ensure that your GNUstep environment is loaded prior
trying to compile anything. A quick check on this is typing
echo $GNUSTEP_USER_ROOT, it should point to something like
/home/donald/GNUstep and not be empty.
When you are done with
SOPE,
you can start to build OpenGroupware.org.
Continue at the OpenGroupware.org section.
