Comment (by kencu):

 adding this to the Portfile fixes the build, while we wait for upstream to
 update the port to work with the new Xcode10+ build system:
 {{{
 # this port has not yet been updated to build with the new build system
 Xcode 10+
 if {${os.platform} eq "darwin" && ([vercmp $xcodeversion 10.0] > 0)} {
     build.pre_args-append -UseModernBuildSystem=NO
     destroot.pre_args-append -UseModernBuildSystem=NO
 }
 }}}
 {{{
 $ port -v installed transmission
 The following ports are currently installed:
   transmission @2.94_0 (active) platform='darwin 18' archs='x86_64'
 date='2019-04-11T07:33:55-0700'
 }}}
