Steve told you that you might need to use LDFLAGS, but it is not the only option you have to set when calling configure. You also need to tell configure where the header files are. Instead of examining the output of "configure --help" or using google, you're just asking to be spoon-fed all the solutions. Try to help yourself by doing some google searching and reading. Anand
