Hi,

With 13.0-RELEASE, I would like to compile and install the Berkeley DB 1.85
source from /usr/src/lib/libc/db however only in its parent directory
/usr/src/lib/libc I could perform the "make" command. Is there a way to
compile specific to the db only? If it's possible then what are the "make"
parameters I should include to invoke?

freebsd@fbsd13:/usr/src/lib/libc/db % ls -lah
