v930 build (OSX 10.3.6) chokes on 'evOptMonoTime' with BOTH '--enable-libbind' & '--enable-libtool'

[OpenMacNews]

hi all,

per an earlier post, after mod'ing "lib/isccfg/include/isccfg/grammar.h", 
building v930 on OSX 10.3.6 as:

(1) w/ '--enable-libtool'

    ./configure --with-openssl --enable-ipv6 --enable-threads 
--disable-linux-caps \
    --enable-libtool

    make

now completes without error. yay!

also,

(2) w/ '--enable-libbind', w/o '--enable-libtool'

    ./configure --with-openssl --enable-ipv6 --enable-threads 
--disable-linux-caps \
    --enable-libbind

    make

completes successfully as well.

but, with BOTH enabled:

(3) w/ '--enable-libbind' & '--enable-libtool'

    ./configure --with-openssl --enable-ipv6 --enable-threads 
--disable-linux-caps \
    --enable-libbind --enable-libtool

    make

'make' fails @:

i've found NO references at all (?) googl'ing on 'evOptMonoTime'.

blindly monkeying around with 'extern's in suspect files hasn't yielded any 
success as yet.

fwiw, v923 build is OK in all (3) cases.

a known issue?
