Fedora have just split off a separate lapack-devel package containing the static library and the symlink liblapack.so. (Mandrake/Mandriva has been doing this for some time. I don't know about SuSE). The up2date service will recognize that it needs to update lapack, but I guess that it won't install lapack-devel, as it doesn't know you need it.
You are right.
It might have been better to do this in the next release, rather than as an update to FC4, but there you go. Better install lapack-devel manually.
lapack belongs to Extras and not to Core. Extras is a rolling release. The change was necessary to allow atlas to compile and interact with lapack. atlas is on the queue to Fedora Extras, it is in the review phase now.
Hmm. Doesn't look like it is actually working, though. Install lapack-devel, configure --with-lapack, and make check dies with running code in 'base-Ex.R' ...make[4]: *** [base-Ex.Rout] Error 1 make[4]: Leaving directory `/home/pd/r-devel/BUILD/tests/Examples' make[3]: *** [test-Examples-Base] Error 2 ....

Error in La.svd(x, nu, nv) : BLAS/LAPACK routine 'DGEBRD' gave error code -10 Execution halted This happens on both x86_64 and x86 installs of FC4. I have a strong sense of deja vu regarding this error.
