I just ran into a second chicken and egg problem.  I just
downloaded the latest pkgsrc tarball on to my laptop running 1.4.3 (I
would upgrade, but it only has 8MB RAM).  When I try to make
pkg_install, it says, "===> This package doesn't support
PKG_INSTALLATION_TYPE=overwrite." Any solutions for this problem?

     The first chicken and egg, which I might as well mention since I'm
writing now, is on a system running 1.5.2, there is a problem compiling
pkg_install...

configure: creating ./config.status
config.status: creating Makefile
config.status: creating nbcompat/config.h
config.status: nbcompat/config.h is unchanged
cc  -I. -I.  -g -O2 -DHAVE_CONFIG_H -c fseeko.c

                 from fseeko.c:30:

                 from fseeko.c:30:

*** Error code 1

Any solutions for this problem?
