Thanks for your report. I worry about possible additional overhead.
Would it make sense to enable this only for the perl-debug build
(/usr/bin/debugperl) ?

As a secondary concern, pushing python (which systemtap-sdt-dev
depends on) into perl build-dependencies doesn't sound very appealing,
but I suppose bootstrappers are used to work around those (re: the
Build-depends-StageN effort et al.)

I assume that enabling dtrace support would not add a runtime hard
dependency on a systemtap package?
