[Symphony] Different solutions when using osi and symphony

First of all, thank you for your help. :)
I tried on different computers and never get -2207.94. :(
Each time I downloaded SYMPHONY-5.4.2 from the website without adding
ThirdParty packages and installed it with ./configure, make and make
install. I then just called "bin/symphony -F problem.mps".

Here is more info about each config.

I will try test it under non debian-based distros.
