pgAdmin install?

I see there are rpms for pgAdmin v1.4.3 on rhel4:

http://www.postgresql.org/ftp/pgadmin3/release/v1.4.3/rhel-4/rpms/

The install chokes on:

[root pgadmin3]# rpm -Uvh pgadmin3-1.4.3-1.i686.rpm
error: Failed dependencies:
        libpq.so.3 is needed by pgadmin3-1.4.3-1.i686
        postgresql is needed by pgadmin3-1.4.3-1.i686
    Suggested resolutions:
        postgresql-7.4.13-2.RHEL4.1.i386.rpm
        postgresql-libs-7.4.13-2.RHEL4.1.i386.rpm

I installed pg from source:

/usr/local/pgsql/lib/libpq.so.4

What is the cleanest path around this?  Should I install from source,
symlink libpq.so.3 and/or --nodeps the rpm install?
