[xml] does libxml2 really needs libdl.so.2 and libz.so.1?

[fred <f nicolet emtest ch>]

hi, 
i have to install libxml2 in our embedded system. I've read, that libxml2 
doesn't need any other library (sorry, i can't find any more where i read 
it...)
I had to install libdl.so.2 and libz.so.1 to make my program run, is it 
normal? 
The only change i made, in my makefile, was the command to link libxml2!

I would be grateful for each brief reply!

Fred
