Interesting.  My IRIX64 6.1 system has both the neqn(1) and tbl(1)
utilities.  It's odd (but irrelevant) that your's doesn't.

The last line above indicates the problem.  The configure script decided
that your system has the xdr_getint() function when (in actuality) it
doesn't.  We'll have to upgrade your configure script.

Try this: edit your configure script, change the following:

        echo $ac_n "checking XDR library for xdr_getint()""... $ac_c" 1>&6
        case "$OS" in
            irix64)
                echo "$ac_t""yes" 1>&6
                HAS_XDR_GETINT=1;;
            *)  echo "$ac_t""no" 1>&6
                HAS_XDR_GETINT=0;;
        esac
        cat >> confdefs.h <<EOF
    #define HAS_XDR_GETINT $HAS_XDR_GETINT
    EOF

to this (remove the 4-blank indentation on each line):

        echo $ac_n "checking XDR structure xdr_ops for x_getint member""... 
$ac_c" 1
    >&6
        cat > conftest.$ac_ext <<EOF
    #line 2184 "configure"
    #include "confdefs.h"

    #include <rpc/types.h>
    #include <rpc/xdr.h>,

    int main() { return 0; }
    int t() {

    struct xdr_ops ops;
    ops.x_getint = (int(*)())0;

    ; return 0; }
    EOF
    if { (eval echo configure:2198: \"$ac_compile\") 1>&5; (eval $ac_compile) 
2>&5;
    }; then
      rm -rf conftest*
                echo "$ac_t""yes" 1>&6
                HAS_XDR_GETINT=1

    else
      rm -rf conftest*
                echo "$ac_t""no" 1>&6
                HAS_XDR_GETINT=0

    fi
    rm -f conftest*
        cat >> confdefs.h <<EOF
    #define HAS_XDR_GETINT $HAS_XDR_GETINT
    EOF

Then, remove the file `config.cache' and re-execute the configure script.

Please let me know if this helps.
