I don't really think this is necessary, but some people seem to.

Title: The default JPEG implementation is libjpeg-turbo Author: Samuli Suominen <ssuomi...@gentoo.org> Content-Type: text/plain Posted: 2012-04-23 Revision: 1 News-Item-Format: 1.0 Display-If-Installed: =media-libs/jpeg-8* libjpeg-turbo is a derivative of libjpeg that uses MMX, SSE, SSE2, and NEON SIMD instructions to accelerate baseline JPEG compression/decompression by about 2-4x on x86, x86-64, and ARM platforms. It is based on libjpeg/SIMD but has numerous enhancements. All users are recommended to migrate: # emerge -C media-libs/jpeg:0 # emerge -1 media-libs/libjpeg-turbo >From here on out media-libs/jpeg:0 is only used as a fallback and at the time of writing this news item, libjpeg-turbo has no known bugs that would require using it.
