Yesterday I have updated "configure.in" not to stop. Obviously
Eric has reverted this change.

I agree not to make opengl mandatory to run grass and to modify
the AC_MSG_ERROR to AC_MSG_WARN related to opengl. Otherwise we
will receive many mails from struggling users.
As > 90% of GRASS don't depend on openGL, there is no need to make
the configure stop if openGL is not found.

Until this is hopefully changed, you can use
configure --enable-opengl=no
