yes:

the DESCRIPTION says:

Package: deSolve
Version: 1.5
Title: General solvers for initial value problems of ordinary
        differential equations (ODE), partial differential equations
        (PDE) and differential algebraic equations (DAE)
Author: Karline Soetaert <k.soetaert@nioo.knaw.nl>, Thomas Petzoldt
        <thomas.petzoldt@tu-dresden.de>, R. Woodrow Setzer
        <setzer.woodrow@epa.gov>
Maintainer: R. Woodrow Setzer <setzer.woodrow@epa.gov>
Depends: R (>= 2.6.0)
Description: Functions that solve initial value problems of a system of
        first-order ordinary differential equations (ODE), of partial
        differential equations (PDE) and of differential algebraic
        equations (DAE). The functions provide an interface to the
        FORTRAN functions lsoda, lsodar, lsode, lsodes of the ODEPACK
        collection, to the FORTRAN functions dvode and daspk and a
        C-implementation of solvers of the Runge-Kutta family with
        fixed or variable time steps. The package contains routines
        designed for solving ODEs resulting from 1-D, 2-D and 3-D
        partial differential equations (PDE) that have been converted
        to ODEs by numerical differencing.

I'll use another solver - but if you want me to investigate further, please
contact me - I think we could take this off-list.
