Thank you, your hint worked!
I commented out the line:
#define HAVE_F77_EXTRA_UNDERSCORE 1
in the R configure script (line 28098 in R 2.7.0 RC (2008-04-15 r45347))
Contrary to what I thought previously, I have gfortran installed:
> gfortran-4.0 --version
GNU Fortran 95 (GCC 4.0.3 (Ubuntu 4.0.3-1ubuntu5))

Not surprisingly, this also fixed the issue with deSolve:
> library(deSolve)
> getNativeSymbolInfo("iniaqua", PACKAGE = "deSolve")$address
<pointer: 0x2aaaaeb3c4d0>
attr(,"class")
[1] "NativeSymbol"
Best regards,
Thibaut.
