The GeoIP CAPI is not installed you should do that. Otherwise try 

    perl Makefile.PL PP=1
    
to install this module anyway. It uses a slower pure perl version 
and you can rebuid it later.

GeoIP must be installed prior to building Geo::IP and I can't find
it in the standard library directories. You can download GeoIP C API from:

http://www.maxmind.com/app/c

If GeoIP is installed, but in a non-standard directory, then use the
following options to Makefile.PL:

    perl Makefile.PL LIBS='-L/home/me/lib' INC='-I/home/me/include'

Note that if you build against a shareable library in a non-standard location
you may (on some platforms) also have to set your LD_LIBRARY_PATH environment
variable at run time for perl to find the library.

If you installed the GeoIP C libraries to the /usr/local/lib directory,
then you may need to add /usr/local/lib to /etc/ld.so.conf then run
/sbin/ldconfig /etc/ld.so.conf
