Ok. However I just tried to build 2.9.0 if the UMFPACK stuff was built 
with the atlas cblas binding. In that case config.log contained messages 
like

configure:7268: gcc -o conftest -g -O2   conftest.c -lumfpack  -lamd 
-lhdf5 -lz -lm  >&5
/usr/lib/gcc/i586-mandrake-linux-gnu/3.4.1/../../../libumfpack.so: 
undefined reference to `cblas_dgemv'
/usr/lib/gcc/i586-mandrake-linux-gnu/3.4.1/../../../libumfpack.so: 
undefined reference to `cblas_dtrsm'
/usr/lib/gcc/i586-mandrake-linux-gnu/3.4.1/../../../libumfpack.so: 
undefined reference to `cblas_zgemv'

etc. So it seems the test as defined in configure.in is not generic 
enough. If there an autoconf macro that just tests for the presence of a 
function (nm like functionality) without actually building anything? Is 
would avoid this issue...
