The file "make.log" contained

It appears that, on your system, the Standard-C math function are not part of
C runtime library.

Please try the following:

1. Go to the top-level source-directory.

2. Execute the command "make distclean".

3. Ensure that the environment variable CPPFLAGS contains the
string "-Df2cFortran" as before.  You do not have to define
its value as "f95": "-Df2cFortran" is sufficient.  For
example

    export CPPFLAGS=-Df2cFortran

4. Ensure that the environment variable LD_MATH is set to a
link-time reference of the math library.  For example

    export LD_MATH=-lm

5. Execute the "configure" script.  Redirect both the
standard output and standard error streams to the file
"configure.log".

6. Execute the command "make". Redirect both the standard
output and standard error streams to the file "make.log".

7. Execute the command "make test". Redirect both the
standard output and standard error streams to the file
"test.log".

8. Execute the command "make install". Redirect both the
standard output and standard error streams to the file "install.log".
