Is it really "/path/to" ? I guess not - if the real path contains white space
it may cause troubles in GRASS 6.2. We have fixed such cases in GRASS 6.4.
Please post the real path you have to better understand the problem.

grass 6.4 requires proj 4.7? The test in configure is:

    if test `expr "$proj_ver" \< 446` = 1 ; then
        AC_MSG_ERROR([*** PROJ.4.4.6 or later is required.])
    fi

which is way older than Proj 4.7.

Yes, this would be an alternative.
