Just a further point the maintainer of OpenEXR seems to be suggesting that the 
warning in regard to OpenEXR may be out of date.. perhaps ImageMagick's 
Makefile needs some modification in the light of the recent changes to 
OpenEXr.. (I am not puttimng myselkf up as an authority here -- I no sweet 
FA<chuckles>.

Also perl on my system is compiled with threads but ImageMagick does not seem 
to realise that or should it be told explicitly?
