ah. ok.
My bad.

I tracked it down to -luuid, one error masked another…

This is a real pain. when developing on x64, and have the 64bit devel packages
for uuid installed, I cannot install the 32bit devel package -.-'

My Bonkers Workaround:

cd /lib/i386-linux-gnu
sudo ln -s $PWD/libuuid.so.1 $PWD/libuuid.so


At least I get it passt configure now.

Thanks
