a minute after your mail, I received the announcement of Fedora 14 al=

ut that src.rpm is probably a reasonable starting point.
I have my doubts regarding a generally useful ROOT build, though: Thi=
s software has tons of build time options, often depending on externa=
l software. A "one size fits all" build would probably depend on a do=
zen or more additional packages most users won't care for. On the oth=
er hand, building ROOT for a certain use case is fairly trivial. This=
may explain why there are few prebuilt packages around.
The user in question needs ROOT for SL 4 with mathmore. It seems that
mathmore needs a newer version of gsl than is provided by SL 4 by default.
Another issue is that users tend to create code that works with a cer=
tain ROOT version only, and any update - even within a major version =
- is likely to cause grief for some of those depending on the previou=
s minor release. At the same time, there will be other users requesti=
ng the very latest release as soon as it's available. Hence, unless y=
ou're catering for a small and well defined user community, you inevi=
tably end up providing multiple releases at the same time, and some m=
echanism to switch between them. I wonder whether the Fedora package =
provides this...
The bottom line is that providing tailored builds for those actually =
requesting them is probably the best way to go. Teaching them to crea=
te those builds themselves may make even more sense.
Maybe ROOT needs a different tailoring model:-) Plugin's come to mind.
The ROOT release schedule has slowed down recently, so things may be =
changing. But I don't think that "a prebuilt ROOT rpm" is a general s=
olution yet.=20
Hope this helps,
