[kde-freebsd] turning threads off in OpenEXR by default

[Mikhail Teterin]

Hello!

I'm contacting you, because the port(s) you maintain depend on OpenEXR.

Although the version 1.2 of OpenEXR was not built with threading support on 
FreeBSD, the current 1.4a includes such support.

This is forcing all users of the library to include thread-support -- perhaps 
gratuitously. The most (in)famous case is with ImageMagick -- when IM builds 
and detects OpenEXR present, it will include support fo OpenEXR format. 
PerlMagick, however, will then fail because it is not linked with -pthread by 
default...

I would like to make threading optional in OpenEXR -- and turn it off by 
default.

Do your ports require a multi-threaded OpenEXR?

Thanks!
