   What issues are you seeing with PKGSRC_SETENV ? I've been using it set
   to env -i since it was added...

Some further investigation revealed that this was my own doing and
applied only to cross-compilation: all of pkgsrc's recursive makes
need USE_CROSS_COMPILE and MACHINE_ARCH passed down to them, which
happens via the environment...unless you clear it with `env -i'.

I think tonight I'll do some surgery to _DEPENDS_INSTALL_CMD to avoid
passing any variables for the native compilation case so that we can
fix security/openssl and any other instances of the problem in that
case for now (sorry for the delay about doing that).

As an aside, would anyone object to making `env -i' the default for
PKGSRC_SETENV?
