Perl was created on Unix-like systems, so to make your life easier on windows:

• avoid spaces in path names, so create a directory 'c:\bioperl' (or whatever you want) and work there;
• keep in mind that the backslash '\' works as an escape character to get special characters (like tabs, newlines) and to get a real backslash, you have to use a double backslash. This will make your paths look weird ('c:\\bioperl\\project').
• when referring to files, you can use a forward slash which you don't need to escape; these are automatically converted, so 'c:/bioperl/somefile.txt' works.

So summarizing: work in 'c:\bioperl' (or similar), put your libraries in, say, 'c:\bioperl\modules', and add the lib-line to your programs:

  use lib 'c:/bioperl/modules';
