octave development version, maybe a bug?

I did encounter what seems like a small bug, maybe only in the build scripts.
(This is Lubuntu 13.10 with all updates, octave source from mercurial of today)

running ./configure
reports (among other) that:

checking suitesparse/ccolamd.h usability... yes
checking suitesparse/ccolamd.h presence... yes
checking for suitesparse/ccolamd.h... yes
checking for ccolamd in -lccolamd... yes
checking suitesparse/cholmod.h usability... yes
checking suitesparse/cholmod.h presence... yes
checking for suitesparse/cholmod.h... yes
checking for cholmod_start in -lcholmod... yes
checking suitesparse/cs.h usability... yes
checking suitesparse/cs.h presence... yes
checking for suitesparse/cs.h... yes
checking for cs_di_sqr in -lcxsparse... yes
checking suitesparse/umfpack.h usability... yes
checking suitesparse/umfpack.h presence... yes
checking for suitesparse/umfpack.h... yes
checking for umfpack_zi_get_determinant in -lumfpack... no
configure: WARNING: UMFPACK not found.  This will result in some lack
of functionality for sparse matrices.
checking for suitesparse/umfpack.h... (cached) yes
checking for umfpack_zi_get_determinant in -lumfpack... no
configure: WARNING: UMFPACK not found.  This will result in some lack
of functionality for sparse matrices.

but suitesparse is there!, also the development files. I have
in /usr/include/suitesparse
the file  umfpack_get_determinant.h, which includes:
....

int umfpack_zi_get_determinant
(
    double *Mx,
    double *Mz,
...
so the configure script must be looking in a wrong place?
