elog undefined?

doing a restore, i get the following error...

[rob@camel bin]$ ./pg_restore -p 5474 -d rms74 RMS74
pg_restore: [archiver (db)] could not execute query: ERROR:  could not
load library "/usr/lib/pgsql/pgcrypto.so": /usr/lib/pgsql/pgcrypto.so:
undefined symbol: elog

the dump was from 7.4 pg_dump against a 7.3 database. the thing thats
bugging me is the undefined elog peice; i have a
/usr/lib/pgsql/pgcrypto.so where specified; is it tossing that error
since that pgcrypto.so was compiled against 7.3 or is this an issue
somewhere in 7.4 pg_restore?
