Looks like you are missing some dependencies - if you look at OpenChromes website(
www.wiki.openchrome.org) they do not really have anything about Solaris but it looks like you need at least autoconf,subversion,automake(not sure if make works in its place),and libtool -
The Xserver part I think should be on the system but you should check, so as far as I know you would have to compile all those yourself unless you can get the binary somewhere -
Good luck
