Sorry, no full output now. Will modify later.
>Description:
I get this error when trying to compile:
gmake[5]: Entering directory
`/usr/ports/lang/erlang/work/otp_src_R15B03/lib/hipe/rtl'
erlc -W  +debug_info +inline -o../ebin hipe_rtl.erl
gmake[5]: *** [../ebin/hipe_rtl.beam] Segmentation fault (core dumped)

FreeBSD 10.0-BETA2 #0 r257166

This happens only when DTrace configuration option is set. If DTrace
is off, all works fine.

Looks like dtrace userland/kernelland are working:
# :/usr/ports/lang/erlang # dtrace -n 'syscall:::entry {
@num[execname] = count(); }'
dtrace: description 'syscall:::entry ' matched 536 probes
dtrace: buffer size lowered to 6m
dtrace: aggregation size lowered to 3m
