[GAP Forum] Loading problem in GAP

[Mathieu Dutour]

Dear all,

when trying to debug GAP packages installation,
it is common to use
SetUserPreference( "InfoPackageLoadingLevel", 4 );

However, if one does that then the error is following:
Error, PrintFormattedString: function is not yet defined in
  ValueGlobal( "PrintFormattedString" )( s ); at
