>Description:
Installation of shared objects is broken if SHLIB_MINOR is undefined,
the problem doesn't exists on NetBSD 4.99.73, it occurs on FreeBSD 6.3
to me, when using current pkgsrc's bootstrap-mk-files-20080808.

>How-To-Repeat:
cat > Makefile << EOF
LIB=    test
SHLIB_MAJOR=    0
#SHLIB_MINOR=   0

SRCS=   test.c

LIBDIR=         /
LINTLIBDIR=     /
LIBOWN!=        id -un
LIBGRP!=        id -gn

.include <bsd.lib.mk>
EOF
cat > test.c << EOF
static const char string[] = "Hello world!";
EOF
make && make install DESTDIR=/tmp

Note that it fails with:

>Fix:
Update pkgtools/bootstrap-mk-files?
