Yes, they could go anywhere in the user's PATH, or even just in the
same directory as the executables without adjusting PATH (though
"Create Executable" would not work right in the latter case).

The installer currently puts the DLLs in the system directory, because
that seems to be the most reliable installation mechanism.

If we start adjusting the user's PATH, for example, then I expect we'd
hear from lots of sysadmins who can't figure out how to install
DrScheme so that it works for lots of users (because they didn't adjust
PATH for every user). That will be true even if the installer process
lets you choose the install mode; many sysadmins will choose wrong,
because playing sysadmin is not their real job.

And more: libmzsch299_018.dll, libmzgc299_018.dll, and ssleay299_018.dll.
