looks like we need a newer gcc.... adding it to the metabug
You may be able to get perl to build by setting: USE="-threads" emerge perl I was segfaulting at the exact same spot with my PPC 604 on perl-5.8.2-r1, and changing the threads flag allowed perl to build. Of course, I'd still prefer my perl threaded... :(
Did # USE="-threads" emerge perl and still breaks at the same place. Why is -lpthread there? rm -f opmini.c cp op.c opmini.c `sh cflags "optimize='-O2 -pipe -mcpu=7400 -maltivec -mabi=altivec'" opmini.o` -fPIC -DPERL_EXTERNAL_GLOB opmini.c CCCMD = gcc -DPERL_CORE -c -fno-strict-aliasing -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -O2 -pipe -mcpu=7400 -maltivec -mabi=altivec -Wall rm -f opmini.c gcc -L/usr/local/lib -o miniperl \ miniperlmain.o opmini.o libperl.a -lpthread -lnsl -ldl -lm -lcrypt -lutil -lc ./miniperl -w -Ilib -MExporter -e '<?>' || make minitest Attempt to free unreferenced scalar: SV 0x101118b0. make: [extra.pods] Error 1 (ignored) ./miniperl -Ilib configpm configpm.tmp make: *** [lib/Config.pm] Segmentation fault !!!

I've edited Makefile to remove -lpthread but that did not changed the failure. I don't know how to debug this since gdb doesn't show any backtrace...
I had a successful compilation without any CFLAGS and with : CFLAGS="-O1 -pipe -mcpu=7400 -maltivec -mabi=altivec" emerge -uv perl my CFLAGS in make.conf are "-O2 -pipe -mcpu=7400 -maltivec -mabi=altivec" so less agressive optimizations worked for me
CFLAGS="-O1 -pipe -mcpu=7400 -maltivec -mabi=altivec" emerge -uv perl compiled successful on my machine. Thanks.
