I would try with
    export LDFLAGS="-L/opt/local/lib"
    export CXXFLAGS="-I/opt/local/include"

But keep in mind that when ghostscript gets updated, you might need to
recompile the binary. Why don't you use
    sudo port install dvisvgm
instead?

I tried to update it just now (the latest version is not in the repo
yet). Two tests fail:
FAIL: DVIReaderTest
FAIL: FontManagerTest
but I'm not sure about how the situation was before.

No. But when neither pkg-config nor cmake know where to find the
binaries, you need to provide explicit hints.

It should not be.

They are spread all over the place. The dylibs in /opt/local/lib
(usually) come from MacPorts, but that's by far not the only place
where you can find them. Usually each .app bundle ships its own copy
of libraries.
