The problem isn't "cfortran"; it's your compilation environment.  See 
below.

According to your "make.log" file:

the system header-file "/usr/include/gconv.h" could not be compiled.
Because a compiler should always be able to compile its own
header-files, this indicates a problem with your compilation
environment.  It could be that the compiler is incorrectly installed.

I suggest that you show the above to your system administrator.

When the compilation environment is fixed, you will need to build the
UDUNITS package from the beginning because a C macro that specifies what
Fortran calling-conventions will be used was not specified.  The C macro
to be defined depends on your operating system and your choice of
Fortran compiler.  There are many examples in the file INSTALL in the
top-level source-directory.  If you will not call the UDUNITS package 
from Fortran, then you can use any of the C macros (e.g.,
"f2cFortran").  Whatever C macro you choose, it must be specified in the
CPPFLAGS environment variable before executing the "configure" script,
e.g.,

    $ CPPFLAGS=-Df2cFortran ./configure >configure.log 2>&1

Please let me know if this helps.
