It is exactly the same problem, yes. Right now, my installer does not
modify the environment at all (like MKL or ACML, actually), and you have
to do it manually (add PATH, or put in system32).

numpy 'dll' (they are technically dll, but are named .pyd on recent
version of windows) are mandatory, and is not a problem: it is handled
by python (whose import mechanism knows how to import dll not in the
path env var).

Well, neither ACML or MKL does it, at least the versions I looked into.
You have to launch a special cmd.exe (like for VS2005) which import the
variables.
