Minh and William, Thank you very much and sorry that I didn't read about the prerequisites before upgrading.
After installing gfortran (I did it system-wide, so setting SAGE_FORTRAN and SAGE_FORTRAN_LIB was not necessary), everything was going smooth. The installation,building, and tuning took some time, but finally ended with no errors reported. Not exactly related to that, but during installation I saw a lot of C code. It seems strange that Ohloh (I got that link from the development page on Sage site) https://www.ohloh.net/p/sage/analyses/latest reports that Sage has -15,017 (a negative number) C code lines. Say, -5 shell script comment lines I can understand (5 lines with negative comments), but how the number of code lines can be negative?
