XnView Software

I have been trying to figure out how to convert pdf to png using the nconvert on my Solaris 10 x86 box. I have ghostscript installed but I am missing something. I keep getting:

ld.so.1: gs: fatal:libcairo.so2: open failed: No such file or directory


Any ideas would be greatly appreciated. It converts all the other file types that I have tried just no luck on the pdf.

thanks again in advance.
