It's most likely because something isn't compiled right. It's just as  
likely gentoo's fault as it is ruby's. Upgraded your gcc lately? Updated  
any of a thousand other dependent libraries lately?

Give revdep-rebuild a go.

If not, give emerge -e ruby a go

Or if you'd actually like to diagnose the problem, try running gdb and  
get a bit more info about your segfault.

run:

ulimit -c unlimited  
ruby segfault.rb

that should produce a core file

gdb ruby core

(gdb) bt

Or something like that.
