Yes.  cargo depends on the libcurl.so.4 library from the curl
package, and it's a run-time dependency.  Since curl lives in the
package installation, its library directory isn't part of the
default search path, so it depends on embedding an rpath in the
executable.

I'm guessing you're using a PREFIX other than /usr/pkg?

Frankly, I don't quite know.

I do know that patchelf from pkgsrc can be used to change the
rpath in an elf executable, a'la

patchelf --force-rpath --set-rpath $RPATH $executable

However, that can at best be characterized as a workaround and
not a "proper fix".  I welcome suggestions for how this should be
done properly.
