Updating package devel/p5-IO-Compress from 2.020 to 2.021

pkgsrc changes:
  - Adjusting dependencies

Upstream changes:
2.021 30 August 2009
      * IO::Compress::Base.pm
        - Less warnnings when reading from a closed filehandle.
          [RT# 48350]
        - Fixed minor typo in an error message.
          [RT# 39719]

      * Makefile.PL
        The PREREQ_PM dependency on Scalar::Util got dropped when
        IO-Compress was created in 2.017.
        [RT# 47509]

      * IO::Compress::Zip.pm
        - Removed restriction that zip64 is only supported in streaming
          mode.
        - The "version made by" and "extract" fields in the \ 
zip64 end
          central record were swapped.
        - In the End Central Header record the "offset to the start of the
          central directory" will now always be set to 0xFFFFFFFF when
          zip64 is enabled.
        - In the End Central Header record the "total entries in the
          central directory" field will be set to 0xFFFF if zip64 is
          enabled AND there are more than 0xFFFF entries present.

      * IO::Uncompress::Unzip.pm
        - Don't consume lots of memory when walking a zip file. This makes
          life more bearable when dealing with zip64.

      * Compress::Zlib.pm
        - documented that memGunzip cannot cope with concatenated gzip data
          streams.

      * Changed test harness so that it can cope with PERL5OPT=-MCarp=verbose
        [RT# 47225]

      * IO::Compress::Gzip::Constants.pm
        - GZIP_FEXTRA_MAX_SIZE was set to 0xFF. Should be 0xFFFF.  This
          issue came up when attempting to unzip a file created by MS
          Office 2007.
