HOWTO fix libjpeg.so.62 problems

If you find that something is not working because libjpeg.so.62 is missing then this may help:

First of all, try to revdep-rebuild: revdep-rebuild --library libjpeg.so.62

This may be all that is needed. Source packages that depend on this library version, no longer available in portage, get rebuilt against a later version of the library.

If the revdep-rebuild does not succeed because some tool of the rebuild process requires libjpeg.so.62, then emerge this package: emerge =media-libs/jpeg-6b-r9

This causes /usr/lib/libjpeg.so.62 to be installed. Retry the revdep-rebuild command above. Hopefully it succeeds. When done, unmerge the obsolete libjpeg: emerge --unmerge =media-libs/jpeg-6b-r9
