Created attachment 228977 [details] patchfile See patch attached. I am not sure about the version of the port. It is not exactly 1.5, because that is broken when building on FreeBSD. Instead I used a specific commit where the upstream fix has been applied. Also, credits to Steve Wills, who helped me debugging qmake trying to strip a shell script in the install stage. I will try to submit the patches upstream. The port was tested with poudriere on the main branch of the ports tree with 13.0-RELEASE-p4 amd64.
