Hello Sue,

I don't know exactly what you mean by saving a lot of space; do you mean
memory-use or disk space?

I'm not a developer, but just suppose that in the future more and more
large computational packages using these libraries get packaged for
Debian; wouldn't it be an advantage to make lapack, cephes, etc. shared
libraries as opposed to static? As far as I understand, the advantage
of shared libraries with respect to memory use increases if the number 
of running programs using that particular library increases (look at the
X-windows libraries for example).

Also: only one version of the library will certainly save lots of disk space,
but if this is the shared library, then *only* people who wish to link the
entire lapack etc. statically into their program (increasing the executable
by several Mb :-( ) will have need of the liblapack.a static lib.

At my work, we use two IBM RS-6000's running AIX for heavy computational work,
and several large quantum chemistry programs are running on them (e.g. 
Gaussian 94, Gamess-UK); If only these programs could share the low-level
mathematical routines, it would save a bit on memory-use IMHO, and even though
they all have memory use (RSS) in the order of dozens of megabytes, every
little bit helps reduce swapping?

This is just my dfl. 0.05 of opinion, of course.
