It's an issue with the linker.  I seem to remember that 8.1 uses the
--as-needed flag to ld, which means it will only link the libraries that
each executable actually uses.

Hmm, poking my build, this doesn't seem to be the case:

$ ldd `which postgres`       linux-gate.so.1 =>  (0xffffe000)       libz.so.1 => /usr/lib/libz.so.1 (0x41c54000)
libreadline.so.5=> /lib/libreadline.so.5 (0xb7f51000)       libcrypt.so.1 => /lib/tls/libcrypt.so.1 (0xb7f23000)
libresolv.so.2=> /lib/tls/libresolv.so.2 (0x41c6a000)       libnsl.so.1 => /lib/tls/libnsl.so.1 (0x41c25000)
libdl.so.2=> /lib/tls/libdl.so.2 (0x4118f000)       libm.so.6 => /lib/tls/libm.so.6 (0x41153000)       libc.so.6 =>
/lib/tls/libc.so.6(0x41019000)       libncurses.so.5 => /lib/libncurses.so.5 (0xb7ee0000)       /lib/ld-linux.so.2
(0x41000000)

This is a fairly recent 8.1, maybe post-beta1.  Not sure what happened.
I certainly don't see the --as-needed in LDFLAGS:

$ pg_config  | grep LDFLA
LDFLAGS = -Wl,-rpath,/pg/install/00orig/lib
LDFLAGS_SL =
