Thanks for looking at this. It sounds like we need some runtime
dependencies as well as the PACKAGECONFIG option. I think the lttng-
tool ust option should be changed:

-PACKAGECONFIG[lttng-ust] = "--with-lttng-ust, --without-lttng-ust, lttng-ust"
+PACKAGECONFIG[lttng-ust] = "--with-lttng-ust, --without-lttng-ust, lttng-ust,lttng-ust"

i.e. force the dependency at runtime as well as buildtime.

Cheers,

Richard
