I have just repeated this on an absolutely fresh up to date F17 machine, 
with no symlink stuff in play.

Steps to recreate:
   CC="ccache gcc" ../postgres/configure --enable-depend --enable-debug   --enable-cassert --with-perl --with-python
--with-tcl--with-libxml   --with-libxslt -with-openssl --with-gssapi --with-pam --with-ldap   make -j 4
 


cheers
