I've got a problem trying to install Date::Calc 4.3 on AP 5.22 Win32.

These lines are from the install.txt file:

# Preliminary steps for use with ActiveState's port of Perl 5.005:
# ----------------------------------------------------------------
# 
# (For the Win32 platform)
# 
# Edit the file "Makefile.PL" and remove all of the "#" characters
# which currently comment out the attributes "ABSTRACT", "AUTHOR"
# and "CAPI".

so I had a look at Makefile.pl ...

# Look at the following line:
#   ($] >= 5.005 && $ eq 'MSWin32' && $Config{archname} =~ /-object\b
+/i ?

There's a funny control character there, a small square(!)What should it be? Is this an error in the makefile or...?

WriteMakefile(
    'NAME'              => 'Date::Calc',
    'VERSION_FROM'      => 'Calc.pm',
    'OBJECT'            => '$(O_FILES)',
    'LIBS'              => [''],   # e.g., '-lm'
    'DEFINE'            => '',     # e.g., '-DHAVE_SOMETHING'
    'INC'               => '',     # e.g., '-I/usr/include/other'
