9.1.1 build failure : postgres link fails

I just got round to updating my laptop to ubuntu-10.4 (32bit), in part
because I kept hitting snags while trying to configure postgres 9.1.1.

The upgrade did in fact solve the dependency issues (though  I was
surprised UUID came along with out the ossp specific impl??) but the
build is having troubles linking the server executable.

Here's my configure line:
./configure --with-pgport=5439 --with-perl --with-python --with-openssl
--with-ldap --with-ossp-uuid --with-libxml --with-libxslt

and the tail of the configure output:

configure: creating ./config.status
config.status: creating GNUmakefile
config.status: creating src/Makefile.global
config.status: creating src/include/pg_config.h
config.status: creating src/interfaces/ecpg/include/ecpg_config.h

ubuntu-10.4 is not the latest of course and comes with gnu make 3.8.1,
but it seems to compile everything then fails to link postgres executable:
