This is not the same as bug# 503854

Also note: I have another x86 system as well as my amd64 system which this package built fine on. This x86 based system is my most minimal system.

"This is not the same as bug# 503854" is wrong and should be "This is not the same as bug# 503584"

[Comment 2 Rafał Mużyło 2014-03-08 07:26:36 UTC]

...well, the *initial* problem is obvious: '-msse2 -mfpmath=sse' disagres with your processor.

The question is "does it need to ?".

Same here on ~x86 and Athlon-XP (sse only, no sse2).

ruby-2.1.1-no-forced-sse2.patch

This patch disables forced sse2 and sse flags.
It is Gentoo policy not to force CFLAGS on users, most people will use -march=native anyway.

[Comment 6 Hans de Graaff 2014-04-14 18:54:21 UTC]

I've applied Andrew's patch to ruby-2.1.1-r1, similar to what Arch Linux is doing. Thanks for the report and for providing the patch.
