  There is no magic: you inherit from Exporter and set up
@EXPORT_OK (and %EXPORT_TAGS, if you need). In wxPerl
the inheritance is in Wx.pm and the EXPORT_XXX setup in Wx::Wx_Exp
(which is autogenerated, but this does not change anything).

  Then there is xx_constants.cpp, which defines a function for mapping
names into constants and a wxPlConstants object to register it with
the main wxPerl AUTOLOAD sub, but the error you see is caused by incorrect
use of Exporter: in the package you do not populate EXPORT_OK
and do not inherit from Exporter.

  Oh, and please do not use Wx::Mini: it is an implementation detail.
