How did _readline_ get into this?

As a curiosity, I tried looking at what Fedora Core 4 does with this.
So I looked for liblapack.a with locate, and it found one in /usr/lib
(on a 32bit system). Then I went to have a closer look at the library
and it turned out not to be there -- apparently the recent update to
lapack had wiped it out, but the locate database was not yet
rebuilt...

This sort of suggests to me that removing the .a file might actually
be a sensible thing to do on SuSE as well.
