I gather that the version of Boost in svn is still 1.34, under:
Modified: trunk/blender/CMakeLists.txt
================================================
you'll find a reference to:


+ find_package(Boost 1.34 COMPONENTS filesystem regex system thread) mark_as_advanced(Boost_DIR) # why doesnt boost do this?
Boost is currently at 1.51.

I'm suspecting that oiio is also at a version that predates support for jpgs. Any reason why? [/u]

Blender now builds against your system Boost libraries. I have Boost 1.49 installed under Debian Unstable; there is also the option of 1.50, but that’s not compatible with the distro-supplied OpenImageIO package.

I should have updated this thread... sort-of forgot about it. I'm following these instructions now:

http://wiki.blender.org/index.php/Dev:2.5/Doc/Building_Blender/Linux/Ubuntu/CMake

in which this is the most significant change:

cd ~/blender-svn
./blender/build_files/build_environment/install_deps.sh

All working a treat now - jpgs are no longer pink. Just wondering if my CUDA toolkit for Mint is out-of-date now... GPU rendering is significantly slower than CPU!
