Disclaimer: this bug has been filed in a semi-automated manner.
When emerging the package media-libs/freetype-2.4.9-r1, the following elog messages are displayed:
* The TrueType bytecode interpreter is no longer patented and thus no
* longer controlled by the bindist USE flag. Enable the auto-hinter
* USE flag if you want the old USE=bindist hinting behavior.
Such messages should only be displayed when the package is upgraded from an old enough package (and possibly for new installs).
These situations can be checked in the ebuild as follows:
if has_version '<media-libs/freetype-1.0'; then
Or, if the message should also be displayed for new installs:
if !has_version 'media-libs/freetype' || has_version '<media-libs/freetype-1.0'; then
Remember to replace 1.0 with the right version number.
See the tracker bug 440214 for more details.
This message is not displayed in the current version.
