Comment (by jmroot):

 My suggested fix would be something like this:
 {{{#!diff
 --- a/_resources/port1.0/group/python-1.0.tcl
 +++ b/_resources/port1.0/group/python-1.0.tcl
 @@ -572,5 +572,8 @@ pre-livecheck {

  pre-test {
      # set PYTHONPATH
 -    test.env-append PYTHONPATH=[join [glob -nocomplain
 ${worksrcpath}/build/lib*] :]
 +    set libdirs [glob -nocomplain -directory ${worksrcpath}/build lib*]
 +    if {$libdirs ne "" && [lsearch ${test.env} PYTHONPATH=*] == -1} {
 +        test.env-append PYTHONPATH=[join $libdirs :]

  }

 }}}
