Disclaimer: this bug has been filed in a semi-automated manner.
When emerging the package sys-apps/usbutils-006, the following elog messages are displayed:
* The 'network-cron' USE flag is gone; if you want a more up-to-date
* usb.ids file, you should use sys-apps/hwids-99999999 (live ebuild).
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 '<sys-apps/usbutils-1.0'; then
Or, if the message should also be displayed for new installs:
if !has_version 'sys-apps/usbutils' || has_version '<sys-apps/usbutils-1.0'; then
Remember to replace 1.0 with the right version number.
See the tracker bug 440214 for more details.

FYI, the < and > operators do string compares, not numeric. so 006<5 would return the wrong result. you need to use -gt and -lt to do numeric compares.

although, numeric compares would break when dealing with -r# and such. would have to use versionator.eclass i think if PMS doesn't provide a compare tool.
