The simplest workaround is to copy c:\strawberry\perl\bin\perl512.dll to c:\strawberry\perl\bin\perl511.dll
I'm thinking a slightly better solution would be to copy C:/strawberry\perl\lib\CORE\libperl511.a to C:/strawberry\perl\lib\CORE\libperl512.a and then change the libperl entry in C:/strawberry/perl/lib/Config_heavy.pl to 'libperl512.a'.
That would be better only in that it brings the libperl setting into line with the convention (of matching the perl version number).
