Try selfupdate with Leopard => Error md5.h is missing

Hi, I have tried a new installation on Leopard. I have installed XCode and the Unix SDK. When I try sudo port selfupdate (I have a version 1.5 installed), I receive this error message: configure: Please install the BSD SDK package from the Xcode Developer Tools CD. configure: error: libmd was found, but md5.h is missing. Well the file md5.h exists (spotlight find it in crypto and sys ...)? Can someone help? Thanks // Jph
