bug in PEAR_PackageFileManager?

In a nutshell, writePackageFile() writes a blank file instead of the XML. I discovered this while running a script I have for a package I develop. In the past, the script has run correctly, reading from the current package.xml, updating it with the info I provide, and writing the new package.xml. When it didn't work, I tried running it again with new summary/description fields to genarate the package.xml, but even this operation resulted in the blank file. Unfortunately, a number of things have changed on my system, so I'm not sure if I can pinpoint any one thing in particular. One thing I know changed: I was on a PEAR 1.4.0a series, I think around a9; I'm now on a11. I'm not sure what version of PackageFileManager I had, nor for XML_Tree or PHP_CompatInfo (if they were even installed). I'm now running with XML_Tree-1.1 and PHP_CompatInfo-1.0 I'm on php 5.0.3 (this hasn't changed). Anybody else seen this? or know of a remedy? -- Matthew Weier O'Phinney | WEBSITES: Webmaster and IT Specialist | http://www.garden.org National Gardening Association | http://www.kidsgardening.com 802-863-5251 x156 | http://nationalgardenmonth.org mailto:matthew@garden.org | http://vermontbotanical.org
