pthreads/dlopen issue when building krb-1.6.3 on AIX 6.1?

[Luke Scharf]

I'm attempting to build MIT Kerberos version 1.6.1 on AIX 6.1.  I'm 
mostly in need of the client libraries and utilities.

I'm using the following special additions to the build environment:

    $ export PTHREAD_LIBS="-lpthread"
    $ export RPATH_FLAG="-Wl,-brtl,-blibpath:"


I'm using the following ./configure command:

    $ ./configure --prefix=/usr/local/krb5-1.6.3
    --enable-log-preauth-logins --enable-login-print-issue
    --with-multihomed-fixes --enable-app-proxy --with-passive-mode-off
    --without-anonymous-ftp


And I get the following results when I run it:

    [snip]
    configure: enabling thread support
    checking for pthread_join in LIBS=-lpthread with CFLAGS=... yes
    checking for joinable pthread attribute... unknown

    configure: disabling static libraries

    $


Does anyone have any suggestions?

Many thanks,
