cannot compile: In `oe_encode': encode.o: undefined references to `vorbis_encode_init_vbr' `vorbis_bitrate_addblock' `vorbis_bitrate_flushpacket'

using Caldera OpenLinux 3.1 ( and replacing it as soon as possible -- they went
institutional on us ), with gcc 2.95.2 Caldera-patched, installed the latest
cURL because vorbis .configure demanded it, ran ldconfig because cURL install 
didn't do it, ran "rm config.cache -f ; ./configure && make" and got dumped.
p.s. I run /tmp noexec, and that's created problems with installing 
OpenOffice, and maybe with other things, too.  If this ( or any other 
filesystem limitations designed to limit damage/hostile-action is creating it, 
then please put something in the README about it, eh? )
