DTrace bindings are missing in FreeBSD 9.0 - CURRENT for userland apps

[István]

Hey,


I am not 100% sure this is the right list to approach with this problem but
let's try this one.

So I am trying to use dtrace on the previously mentioned system, I followed
the usual kernel rebuild process using the following wiki:

http://wiki.freebsd.org/DTrace

Dtrace works fine and I am able to trace the kernel.[1]


My problem is: I can't trace any user land application including PostgreSQL
and Ruby.

I added the following lines to the /etc/make.conf as it is written in the
wiki:

STRIP=
CFLAGS+=-fno-omit-frame-pointer

I compiled both of the softwares and trying to trace them but there are no
bindings in the dtrace -l ouput


# dtrace -l | grep -i ruby

i might have overlooked something important but not sure what.

Any help is appreciated. Pls cc my email since i am not on this list.


Thank you in advance.

I.
