It works, obviously I hadn't done a make clean as I thought I had. I did 
have other build errors earlier which disappeared after I did "rm 
/usr/lib/libmyth*". I have had similar problems building the hamradio 
VOIP package svxlink, cured by deleting the previously installed 
libraries. From what I could tell, it shouldn't have been referencing 
those libraries, but should have been using the ones in the build package.
As it's the first time I'm seeing such things, makes me wonder if it's 
something introduced with gcc-4.1.0/glibc-2.4-12 used in Opensuse 10.1Beta.
Regards
Sid.
