I agree. Packagers should just install the full ruby install. Debian
had these same problems, I don't know if they fixed it, because I
always install from source now.
I know the argument is that there's some stuff you may not want on a
server install for security reasons, but that should be a special
package for people who actually care (in other words, sysadmins who
should probably be building from source anyway). For the other 99% of
us who want a full "just works" install on every machine, the full
install should be the default.
