replyed too soon and too tired, after reading the ebuild[1] for 
libjpeg-turbo I can see that media-libs/libjpeg-turbo-1.2.1 is 
configured --with-jpeg${JPEG_ABI} with JPEG_ABI=8.

libjpeg-turbo should be ABI (API?) compatible with libjpeg-8 released 
january 2010.

Kevin, while the rejection of libjpeg-9 get my unconditional support 
(worked with tiff from fax in the past), I think Fedora should support 
<=libjpeg-8d ABI unless even these produce (like jpeg-9) unreadable jpegs.
This because it actually the maximum both libraries support and probably 
what will be best supported in the future.
Am I wrong?

[1] an ebuild is a bash like file of instruction of how to build a 
package, url: 
http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/media-libs/libjpeg-turbo/libjpeg-turbo-1.2.1.ebuild?view=markup
