--------------------+-------------------------
 There is a typo in the Portfile with the default variants.

 {{{
 if {![variant_isset python36] && ![variant_isset python38]} {
     default_variants +python38
 }
 }}}

 Should be:

 {{{
 if {![variant_isset python36] && ![variant_isset python37]} {
     default_variants +python38
 }
 }}}
