Subject: | Makefile.PL assumes that shared libs are .so on !Win |
In Makefile.PL searching for libusb,
return 1 if defined $dir && ($^O =~ /win/i ? -e "$dir/libusb.lib" : -e "
$dir/libusb.so") ;
Not all unixen, never mind all not windows operating system have shared
libs ending in .so, some have different extensions, others append the
version number.
