The thing to look first is the library search path in the ld.so hints, which is output at the second line of ldconfig -r. I think that you have /lib before /usr/local/lib/gcc46 in your setup. This guess is confirmed by the numeration of the two instances of gcc_s above. Either change the config, or use -rpath. AFAIR, ldconfig -m adds the directory at the end of the search list. --+svXpSx+RSEd8UhP Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (FreeBSD) iEYEARECAAYFAk9D6TEACgkQC3+MBN1Mb4hjugCfRXYXIAPgTsF+A2DKUq5bf1A2 A70AoMle3bjhdxU4Nw7+h5XYfzgi6/tP =PhNe -----END PGP SIGNATURE----- --+svXpSx+RSEd8UhP--
