Getting spfmilter installed

I am trying to get spfmilter installed on my Ubuntu 13.04 machine.

Previously on 10.10, I was able to install it via apt-get: Version: 1.99+0.=
97-3build1

But it's not found on 13.04.

So I downloaded libspf2-1.2.10.tar.gz and an configure/make/make install an=
d that was fine.

Then I downloaded spfmilter-1.0.8

I run ./configure on spfmilter-1.0.8 and it gives me:
checking spf2/spf.h usability... no
checking spf2/spf.h presence... yes
configure: WARNING: spf2/spf.h: present but cannot be compiled
configure: WARNING: spf2/spf.h:=A0=A0=A0=A0 check for missing prerequisite =
headers?
configure: WARNING: spf2/spf.h: see the Autoconf documentation
configure: WARNING: spf2/spf.h:=A0=A0=A0=A0 section "Present But Cannot Be =
Compiled"
configure: WARNING: spf2/spf.h: proceeding with the preprocessor's result
configure: WARNING: spf2/spf.h: in the future, the compiler will take prece=

checking for spf2/spf.h... yes
checking for SPF_destroy_config in -lspf2... no
libspf2 is required to build this program.

If I try to run make on spfmilter-0.97 I get:

gcc -g -O2 -L/usr/local/lib -o spfmilter spfmilter.o match.o iparray.o -lpt=
hread
spfmilter.o: In function `add_fallback':
/root/spfmilter-0.97/spfmilter.c:518: undefined reference to `lib_init_fall=

/root/spfmilter-0.97/spfmilter.c:1580: undefined reference to `lib_fini_con=
nection_data'
spfmilter.o: In function `spf_eoh':


I also tried to download libspf0 but the website at www.libspf.org is dead.
