I was unable to duplicate your problem on our OSF/1 system:

    $ uname -a
    OSF1 dana.unidata.ucar.edu V5.1 1885 alpha

I also used /bin/cc.  My make(1) was /usr/bin/posix/make.

I noticed that your C compiler issued a warning that mine didn't:

    making `all' in directory /short/e93/jlr581/udunits-1.11.7/src/lib

    ln -s ../port/misc/udalloc.c .
    ln -s ../port/misc/udalloc.h .
    cc -c -O -I../port/misc -I../port/cfortran 
    /udunits-1.11.7/etc/udunits.dat"'  -std utlib.c
    cc: Warning: utlib.c, line 1081: In this statement, "getenv(...)" of type 
     is being converted to "pointer to const char". (cvtdiftypes)
            path    = getenv("UDUNITS_PATH");

This could be the problem because -- on my OSF/1 system at least -- an
"int" is 32 bits while a "char*" is 64 bits.

The getenv(3) function should be declared by the <stdlib.h> header-file.
Your "configure.log" file seems to verify this:

    checking C header file <stdlib.h> for function getenv()... declared
    checking for string.h... yes

Yet the above warning indicates that "getenv()" is not declared. Would
you please investigate this by making the file "utlib.i" and searching
it for "getenv", e.g.,

    $ cd lib
    $ make utlib.i
    cc -E -I../port/misc -I../port/cfortran 
  -std utlib.c > utlib.i
    $ grep getenv utlib.i
    extern char     *getenv  ( const char * ) ;
            path    = getenv("UDUNITS_PATH");

What does the above show on your system?
