The preferred way, I guess, is to use the standard DESTDIR automake
variable when installing. Instead of typing 'make install', type 'make
DESTDIR=/some/dir install'. /some/dir may be the mount point of your
laptop filesystem on your development platform, or a temporary dir which
you will copy from one platform to the other.

The compiler used for compiling RTAI has to be the same as the one
which compiled the Linux kernel. The Linux kernel will refuse to load
RTAI modules otherwise.
