vanilla sources.
Where did you get fmpq_poly 0.1.9 from? (The version in Sage is 0.1.8.)

Just change `-lmpir` to `-lgmp` in the `makefile` (at the top; one
occurrence).
I guess you already managed, but to build the FLINT library outside of
Sage from the vanilla sources, you can use e.g. (on non-Darwin / non-
Cygwin systems):
{{{
#!sh
make PREFIX=/usr/local FLINT_GMP_LIB_DIR=/usr/lib FLINT_LIB=libflint.so
library
# optionally:
make PREFIX=/usr/local FLINT_GMP_LIB_DIR=/usr/lib FLINT_LIB=libflint.so
check
}}}
which produces the library in FLINT's top-level directory.
