[cairo] Cairo 0.5.0 problem compiling - libiconv_open erro

[Doug]

When I try to compile the new cairo 0.5.0, I get the
error
Undefined Symbol          first referenced in file
libiconv_open           
/usr/local/lib/libfontconfig.so
libconv                 
/usr/local/lib/libfontconfig.so

Any ideas as to what could be causing this as my old
cairo version compiled and worked.  I am on Solaris
2.8 on a sparc

thanks
