Does it make sense to switch to -CURRENT for that? cu Adrian -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFIe0htqpMUYrZbQBERAvBpAJ9eTtDCdTJYcF2v1DtAr3vTSdartgCgoL1G aWEdX1ZHHl8pUZ5O87xJf2g= =EvmR -----END PGP SIGNATURE-----
