My O2's been building stuff from pkgsrc for the last hour without any
of the glitches we've seen before ( fingers crossed )
Building perl now, let's see how that goes.
I'm using an n32 userland and kernel, with the bus_dma.c changes
tsutsui@ mentioned adapted to sgimips/bus.c, gcc 4.5, gmp patched as
posted earlier.
Here's the dmesg:
pmap_steal_memory: seg 0: 0x38 0x38 0x60 0x60
pmap_steal_memory: seg 0: 0x3a 0x3a 0x60 0x60
pmap_steal_memory: seg 0: too small for 1205 pages
pmap_steal_memory: seg 1: 0x60 0x60 0x68 0x68
pmap_steal_memory: seg 1: too small for 1205 pages

Only problem so far: pkgsrc complains about $MACHINE mismatch mipseb
vs. mips64eb. Yes I know that's unrelated ;)
have fun
