it seems that different espresso versions load different flags for AR in 
the iotk Makefile

v.3.2:    loads ARFLAGS_DYNAMIC  in iotk/src/Makefile,
so, you can try so properly set this variable 
(something like ARFLAGS_DYNAMIC=ruv   I hope) if it is not set

the reason is explained in make.sys as:

# ar command and flags - for most architectures: AR = ar, ARFLAGS = ruv
# ARFLAGS_DYNAMICS is used in iotk to produce a dynamical library,
# for Mac OS-X with PowerPC and xlf compiler. In all other cases

current cvs:  loads ARFLAGS in iotk/src/Makefile and not

anyway, I think your case is the former
