newbie question:make ***[all-recursive]?

[kcross]

I've been trying to install various versions of ecasound and ecasound (cvs 
and plain tar.gz alike) on YDL2.2(Pb G3) and I get:

cd . && autoheader
configure.in:199: warning: AC_TRY_RUN called without default to allow cross

It can't find certain files but as a newbie I'm unsure what to do.
Any help would be much appreciated
