relocation error

[w00t]

I am running Suse 9.0 and have been working with postgresql 7.3.3

When I run psql as psql -v or psql -V and even psql --help I get a
relocation error

psql: relocation error: /usr/lib/libreadline.so. 4: undefined symbol: BC

Is there anyway to fix this with out reinstalling postgresql.

Thanks,
