Pierre-Alain Joye has two new posts on his blog today, both dealing with the PEAR installer, noting an "issue" that came up with it and PHP's safemode and a new version of it to correct a rather large bug.
The first post makes a point about bug reports and testing before sending. He recieved a report that the PEAR installer (go-pear) was broken when safemode is on. Fortunately, it turned out to be a lack of knowledge on the user's part and just being a matter of permissions.
Post number two talks about the newly released version of the PEAR installer, including a new version of the Web frontend (0.5.1). The new installer version corrects a bug where the server will have to request channel servers for every command over and over again - all due to the lack of a cache directory.
