Using the 4.2.4 I had available, I got gcc-4.6.1 installed.

Still doesn't pass perl build:

          CCCMD =  gcc64 -DPERL_CORE -c -mpa-risc-2-0 -DDEBUGGING
-D_HPUX_SOURCE -fno-strict-aliasing -pipe -I/usr/local/pa20_64/include
-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64  -g -O  -Wall -W -Wextra
-Wdeclaration-after-statement -Wendif-labels -Wc++-compat -Wwrite-strings
{standard input}: Assembler messages:
{standard input}:35254: Error: Invalid operands
make: *** [pp.o] Error 1

Would it help to re-build binutils with gcc-4.6.1?
