Guys,

Hmmm. I appear to have had a compile error with that alpha5 tarball,
in elog.c. No special options on compile, except an alternate directory
and port.

Ubunutu 9.10 server
GCC 4.3.3
Tries both:
../configure --with-pgport=5490 --prefix=/usr/local/pgsql/9.0/
and:
../configure --with-pgport=5490 --prefix=/usr/local/pgsql/9.0/
--enable-debug -enable-cassert

make[4]: Entering directory
