Speaking about this one "duplicate symbol" issue, as a user I would probably be happy to see something close to Sean suggestion with additional info.

What about if we have next form here:
/usr/bin/ld: error: byte_copy.c:(.text+0x0): duplicate symbol 'byte_copy'
/usr/bin/ld: error: byte_copy.c:(function byte_copy): previous definition was here
note: 'byte_copy' definitions were found both in usr/ports/sysutils/safecat/work/safecat-1.13/byte_copy.o and usr/ports/sysutils/safecat/work/safecat-1.13/str.a(byte_copy.o),
check that you do not include objects files twice.
