Re: 8.0 Dynamic Linker Broken? (Was: [PATCH] SASL problems with spnego on 8.0-BETA4)

Actually this may mean quite otherwise.
What I saying is if some code (eg. libsasl) dlopen() libgssapi as
RTLD_LOCAL then later attempt to load libgssapi_xxx inside libgssapi may
fail because of this:

$ldd /usr/lib/libgssapi_spnego.so
/usr/lib/libgssapi_spnego.so:
        libasn1.so.10 => /usr/lib/libasn1.so.10 (0x28300000)
        libc.so.7 => /lib/libc.so.7 (0x2808f000)

I would expect to see libgssapi.so.10 dependency here.
