Yes, I think Dmitri is right. I just remembered that GLPK also does not 
come as a dynamic library. When I tried compiling octave with GLPK, it 
just statically compiles GLPK into liboctave as demonstrated here with 
UMFPACK. I seem to remember that the resulting binary was a big step up 
in size compared to the previous version, which would be expected.

While we're on this topic, I thought I'd mention that I did a little 
research on GLPK because I intend to package it for Fedora Extras 
(eventually). According to the mailing lists, it was claimed at one time 
that GLPK was only a static library because the code was not reentrant. 
I think I recall that that is supposedly no longer true of recent 
versions. However, the maintainer never changed the makefiles to add a 
shared library. I asked about the possibility about a month ago on the 
GLPK mailing list and never received a response. It unfortunate that 
some software projects don't have maintainers as resposive as octave 
does :).

So, if anyone is interested in hacking the GLPK makefiles to generate a 
shared library, I would be very interested in the result.
