OK I'll look into that some more: however the intension was that HAVE_ICU 
and ICU_PATH should not be mixed, HAVE_ICU is designed for Unix like systems 
that have the icu binaries installed in the usual std locations under the 
std Unix naming convention for ICU.  I'll try and tweak the logic so that 
ICU_PATH takes precedence in that case.

Thanks, John.
