Tough luck on the users of such Linux distributions, but far from
optimal performance seems to be their way; e.g., Debian has disabled
dynamic superinstructions in Gforth by default on all platforms since
forever (slowdown by a factor of 2), because at one time that was a
workaround for a bug on one platform.
Anyway, people who distribute software as source code, particularly
those who distribute scientific software normally design it for people
who install it from source code. If someone else divides the
installation step into several stages, it's those people's job to
divide it correctly.
