Despite the oft-misinformed outlook of Windows users, who have been
hardened by enduring years of incompatible OS upgrades, the various
different linux distributions are actually, for the most part, just
different flavors of exactly the same thing, diverging most notably in
GUI themes and control tools. Most programs depend on the underlying
distribution primarily through shared libraries, with perhaps a weak
dependency on a shell for install scripts. Sometimes these
dependencies are very complex, and thus a program can seem tied to
individual distributions (RedHat 7.x, say). In reality, it's just
tied to a specific (large) combination of shared libraries.

The key point here is that IDL doesn't actually depend in the least on
all those RedHat extras; in fact it's fairly self-sufficient (bundling
it's own Mesa OpenGL library, for instance). It's dependencies are
limited to the C library (glibc), C++ library (libstdc++) and several
X11 libraries. So really, RSI could simply specify a range of glibc,
libstdc++, and XFree86 versions, and be confident that *any*
distribution with compatible versions will work. This is the standard
practice in the open-source world, but I suppose there's fear of
confusing the potential buyer.
