Getting anything by git is impossible on dialup. 10Mb per hour, 4 hour 
maximum connection.
Thus the act of getting stable releases does still have a purpose.

Tried that, wasn't the problem.
Upgrading the compiler was a major task, but seeing the new precision 
math modules now required, this problem I encountered makes complete 
sense now.

Solved. Requirement of new gcc which requires mpfr,mpc, and gmp does 
solve the problem.
