Indeed, I have included mmxext into CPU_FLAGS_X86 |
| 63 |
and the above error message disappeared. |
| 64 |
|
| 65 |
My guess is that CPU_FLAGS_X86 is used only when |
| 66 |
emerging x32 libraries while -match=native is used |
| 67 |
for x64 libraries. When both x32 and x64 libraries |
| 68 |
appear in the same package, portage somehow |
| 69 |
notices the conflict and reports it. |
