Log Message:
Updating package in devel/p5-Data-Alias for CPAN module Data::Alias from
1.15 to 1.16.

pkgsrc changes:
- Add USE_LANGUAGES=c to remark it's an XS module requiring a C compiler

Upstream changes:
version 1.16; 2011-11-17
  * bugfix: use supported API to put destructor calls on the save stack
    (the unsupported way used before was wrong for 64-bit systems on
    perl 5.13.1 and later)

  * document the behaviour of "alias return" in more detail

  * convert .cvsignore to .gitignore
