[Pgpool-general] problem to build pgpool II 2.3.3 with postgresql 8.4.4

[Tatsuo Ishii]

What does ldd show against libpq?
Mine is:

$ ldd /usr/local/pgsql/lib/libpq.so.5
	linux-gate.so.1 =>  (0xffffe000)
	libssl.so.4 => /lib/libssl.so.4 (0xb7f4c000)
	libcrypto.so.4 => /lib/libcrypto.so.4 (0xb7e43000)
	libcrypt.so.1 => /lib/libcrypt.so.1 (0xb7e15000)
	libc.so.6 => /lib/i686/libc.so.6 (0xb7cf3000)
	libdl.so.2 => /lib/libdl.so.2 (0xb7cef000)
	/lib/ld-linux.so.2 (0x80000000)

Do you have libdl.so shown?
