 `port gohome` returns lots of lines of errors if the port doesn't define
 the `homepage` variable. Yes, that variable is required according to `port
 lint`, but it would still be nice if this error spew could be reduced down
 to just one line:

 {{{
 $ port gohome arts
 can't read "portinfo(homepage)": no such element in array
     while executing
 "set homepage $portinfo(homepage)"
     ("gohome" arm line 5)
     invoked from within
 "switch -- $action {
                 cat {
                     # Copy the portfile to standard output
                     set f [open $portfile RDONLY]..."
     invoked from within
 "if {[file readable $portfile]} {
             switch -- $action {
                 cat {
                     # Copy the portfile to standard output

         # If we have a url, use that, since it's most specific, otherwise

     (procedure "action_portcmds" line 12)

     invoked from within
 "if { [llength $remaining_args] > 0 } {

     # If there are remaining arguments, process those as a command

     # Exit immediately, by default, unless..."
     (file "/mp/bin/port" line 3207)
 }}}

 I'm using MacPorts trunk @38780.
