Could be, but specifically in my case, mozilla does depend on them (for
rendering stuff), and the checking at configure time is also a bit complex.
So the dependecy is no at build time only but also at run-time. Anyways , I
intend to ask on a mozilla mailing list about how hard would be removing
such dependency ?

The problem is the "AC_PATH_XTRA()" configure test. It defines the

> libraries. The configure scripts for at least debian and maemo
> distributions returns "-lSM -lICE" for this variable. Configure scripts
> which try to be correct and portable and thus use this variable will
> automatically link against this libraries - even if they do not use
> them. I removed the use of X_PRE_LIBS temporary to avoid linking this
> libraries.

still wordering why are these libraries available on devel rootstrap (so it
makes possible to your app to depend on them) but not on the device image ?
