Unzip in pkgsrc is version 5.52, but version 6.0 has been out
for nearly a year.
$ l bigzipfile.zip
-rw-r--r-- 1 rhialto wheel 5503854812 Feb 27 21:38 bigzipfile.zip
$ unzip -l bigzipfile.zip
warning [bigzipfile.zip]: 1199032651 extra bytes at beginning or
(attempting to process anyway)
error [bigzipfile.zip]: start of central directory not found;
(please check that you have transferred or created the zipfile in the
appropriate BINARY mode and that you have compiled UnZip properly)
Strangely enough, the version of Zip 3.0 in pkgsrc is apparently
able to *create* 64-bit archives: output from zip -v includes
ZIP64_SUPPORT (use Zip64 to store large files in archives)
Workaround: use 7zip.
Fix: update unzip to version 6.0:
New features in UnZip 6.0, released 20 April 2009:
* Support PKWARE ZIP64 extensions, allowing Zip archives and Zip
archive entries larger than 4 GiBytes and more than 65536 entries
within a single Zip archive. This support is currently only
available for Unix, OpenVMS and Win32/Win64.
