Buenas i was trying to install the latest gem-cvs. unfortunately the ./configure stucks on Altivec: ... enabling "register struct return" allows to make use of FreeFrame-effects without recompiling them might break things, if you are using several different compilers checking whether compiler accepts "-O3"... yes checking whether compiler accepts "-fno-builtin"... yes checking whether compiler accepts "-falign-loops=16 -funroll-loops"... yes checking whether compiler accepts "-ffast-math"... yes AltiVec: ...... ... i also tried to ./configure --disable-altivec to avoid this plugging but no success. thanks for any clues olsen
