Thanks. In the future, please send this type of message to the coders list, or
post it in a bug report, instead of sending it to any particular developer(s).

Sppoky. I just made this change yesterday, for unrelated reasons. $(PERL) is
now defined in all makefiles.

No, dir is set to $PWD, and the $$ is needed in a makefile. I suspect the
problem is that the net-snmp-config in the src path is not executable at the
time that the perl makefiles are built. Try the attached patch, and see if it
helps (you'll need to regenerate the makefile).

I'll let Wes or someone else comment on these changes, if the attached patch
doesn't help you.
