gcc version selection

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

I'm still confused by gcc version selection - how is it meant to work?

On NetBSD 5/i386 (i.e., a system with gcc 4.1.3):

# cd /usr/pkgsrc/graphics/openexr
# make show-var VARNAME=GCC_REQD
4.3 2.8.0
# make show-depends
{gcc49,gcc49-libs}>=4.9:../../lang/gcc49-libs
ilmbase>=2.2.0nb1:../../graphics/ilmbase
#

So, how did we get from 4.3 to 4.9?

Cheers,

Patrick
