[ruby-core:67128] Re: Ruby 2.2.0 Released

I can't install it in any of our Ubuntu servers using rbenv:

relocation R_X86_64_32S against `.rodata' can not be used when making a 
shared object; recompile with -fPIC

or:

/usr/bin/ld: ./libffi-3.2.1/.libs/libffi.a(raw_api.o): relocation 
R_X86_64_32S against `.rodata' can not be used when making a shared 
object; recompile with -fPIC
./libffi-3.2.1/.libs/libffi.a: error adding symbols: Bad value
collect2: error: ld returned 1 exit status
make[2]: *** [../../.ext/x86_64-linux/fiddle.so] Error 1

I couldn't test in my Debian sid environment since I use RVM and RVM 
tries to install 2.2.0-rc1 when I ask it to install 2.2.0 after rvm get 
head.

Any ideas on what could that be?
