RedHat with Postgres 8

I read in FAQ that pgadmin 1.1 doesn't work with Postgres 8, only 1.2 
version.
I have RedHat 9 ... In your donwload site, I can get only 1.2 version of 
pgadmin for Fedora (pgadmin3-1.2.0-cvs20040917).
I tried to install this on my RedHat and I got this 2 error messages:

libXinerama.so.1 is needed by pgadmin3-1.2.0-cvs20040917
libXxf86vm.so.1 is needed by pgadmin3-1.2.0-cvs20040917

How can I install pgadmin III to work with RedHat 9 and Postgres 8 ?

Thanks,
