I will do a full test (building / installing / testing) some extensions (PEAR and PECL) and if all is ok, I will push it to rawhide (probably this week-end).
Done. PEAR 1.7.0 is available in rawhide.
I've build / install / uninstall / test some PECL and PEAR extensions without any problem.
Please check you extension to verify if all is ok.
Regards
