Do you mean the build system of flint or of Sage? If the former then I think the only thing I can think of is to rename libflint.so to libflint2.so. This is easy to do of course. Simply change the relevant line in Makefile.in and reconfigure. I believe the only name clashes should be between fmpz and fmpz_poly between the two flints. One library order should give you flint 1.5 fmpz access, the other library order should give the other fmpz. Note that in order to get all the features of flint 1.5 into flint2 we need the new FFT which I started writing nearly 1.5 years ago. This will be going into MPIR, the next release for which is scheduled in early September. How is Sage doing with keeping up with the MPIR releases? I haven't been keeping track lately. flint2 needs a pretty recent release of MPIR and similarly for mpfr. I assume Sage did not upgrade to flint 1.6. This is a good thing as it will be a very long time before we are able to cover factorisation of polynomials over the integers in flint2. It'll be worth waiting for though.
