Problems upgrading sysutils/mc

[Stefano Marinelli <postnet%dragas.dyndns.org@localhost>]

Hello,
I can compile sysutils/mc but when installing, it says:
ERROR: [check-interpreter.mk] The interpreter "/usr/bin/env" of 
"/pkg_comp/obj/pkgsrc/sysutils/mc/default/.destdir/usr/pkg/libexec/mc/extfs.d/s3+"
 is not allowed.

I think there's something wrong in it.

Bye,
Stefano
