--- Comment #9 from Dimitry Andric <dim@FreeBSD.org> ---
What happens with perl seems to be the same as bug 258872, i.e. dtrace is d=
oing
something magical with the object files during the perl build, and this cau=
ses
duplicate symbols:

ld: error: duplicate symbol: __dtraceenabled_perl___op__entry
>>> defined in mpdtrace/perlmini.o
>>> defined in mpdtrace/dump.o

ld: error: duplicate symbol: __dtraceenabled_perl___op__entry

ld: error: duplicate symbol: __dtraceenabled_perl___sub__entry
>>> defined in mpdtrace/pp_hot.o
>>> defined in mpdtrace/pp_sort.o
cc: error: linker command failed with exit code 1 (use -v to see invocation)

However, I've always failed to understand dtrace, and the only workaround(s=
) I
know are always to turn the DTRACE related options off.

Is there anyone who understands dtrace, and can offer assistance with this?
