#52: bonmin/ipopt execs not constructed on osx 10.10.1

Comment (by compiler):
First of all, thank you for your reply. I do not have AMPL and do not
intend to use it in the future either. So I was trying to get executable
and didn't think I would need to obtain ASL as I am not going to use it
with AMPL. The bonmin manual clearly states that the following
instructions:
" BONMIN is compiled and installed using the commands:
./configure -C
make
make install
This installs the executable bonmin in Bonmin-1.8/bin
"
Hence, the confusion.
As a second question, following your reply, I was also able to get
executables with cplex. I do set "bonmin.milp_solver Cplex" however it
continues using cbc... here is an output of bonmin solve command with a
bonmin.opt file in working directory (with the cplex option in the .opt
file):

Bonmin 1.8.0 using Cbc 2.9.0 and Ipopt 3.12.0
This program contains Ipopt, a library for large-scale nonlinear
optimization.
