Sounds like both problems need some custom linker flags for DragonFly.

There are multiple approaches to solving the library load path, but
AFAICT the pkgsrc people have used the NetBSD approach which is to
link the library load path right into each individual executable.

E.g. just do readelf -d <any random executable> and you should see an
entry for RPATH which tells the linker/loader which directories to
search for any needed dynamic runtime libraries.

When I do that on linux I don't see the RPATH -- instead, the linker/
loader relies on the /etc/ld.so.conf approach to searching for libs.

Anyway, to embed the RPATH into an executable you just add the gcc
flag -Wl,-rpath=<comma-separated-paths> to the list of loader flags
in the Makefile.

Grepping thru some pkgsrc packages should supply lots of examples.

Same for -lpthread versus -pthread linker flags.
