Dear Simon, 

thank for your answer.

I was just tring to draw a png :
==================
png("foobar.png")
plot(rnorm(10,3))
dev.off()
=================

which returns :

=================
libpng warning: Application was compiled with png.h from libpng-1.2.26
libpng warning: Application  is  running with png.c from libpng-1.4.1
libpng warning: Incompatible libpng version in application and library
=================



Then, after reading your answer, I've restarted R to check all libraries and the problem seems to be solved .... even with all the library I was using ...

Sorry for disturbing and many thanks :)

Cheers
