They do not know to check in /opt/local/include automatically so you have to tell them to check there. The normal should-work-everywhere way to do that is by putting -I/opt/local/include into the CPPFLAGS environment variable. If that causes problems for the myth build, that is a bug in the myth build system that the myth developers should fix.<br><br><blockquote type="cite">So I’m now building the “Myth-blessed” way! ;)<br></blockquote><br>It would be silly of them to say that it is not supported to build myth with dependencies installed in a prefix other than /usr.<br><br><br><br></body></html>
