I have trouble with installing Coro module.
.......
^
dmake: Error code 129, while making 'State.o'
dmake.exe: Error code 255, while making 'subdirs'
MLEHMANN/Coro-6.43.tar.gz
C:\STRAWB~1\c\bin\dmake.exe -- NOT OK
Stopping: 'install' failed for 'M/ML/MLEHMANN/Coro-6.43.tar.gz'.
Full install log is here: log
Version 6.46 reports that it "restore[s] portability to perls with windows fork emulation". That means Strawberry Perl. It may solve your problem.
