I feel that one point in the cross-build related documentation
wasn't emphasized enough, and may have caused this sort of error
when one tries to build multiple versions of R: the version of
native R used *must* match the version of cross R one intends to build.

The user mentioned that he tried building R 2.3.1, 2.4.0 and 2.4.1 ;
the only way it would work successfully would be that he also has
linux native R of all three of those versions.
