(sort of off-topic, but it's about perl versions).
The libmail-sender-perl that is mentioned Dann's writeup under howto install Ecore is an old version (the one on the everydevel site is) superceded by my own packaging; I have received permission from the author, and another version is available at:
http://jay.bonci.com/debian.
However, you have to realize that ecore requires perl-5.6.1 now, because it is an incidental dependancy of the newer versions of libxml-generator-perl. A .deb of ecore is also at my site, and I'd personally love it if you tried it (it requires woody). Better documentation is available through myself, and/or at the Everydevel website at
http://everydevel.com.
The number-one fix to all of this is to set your distribution to be "testing" and not "stable", because that opens up the later version of perl, and will allow the deb to install, but now we're getting into debian stuff.
