>Description:
I am using pkgsrc on Linux to replace parts of the Linux userland one-by-one.  
Cyrus SASL, OpenSSL and OpenLDAP are installed from pkgsrc with older versions 
sitting under /usr and /usr/local.  The port mail/sendmail appears to install 
correctly, though none of the executables run due to missing libraries.  
Specifically, it cannot find the ldap libraries that were installed into 
/usr/pkg/lib as the SONAME is different than installed under /usr/lib.

$/usr/pkg/libexec/sendmail/sendmail
/usr/pkg/libexec/sendmail/sendmail: error while loading shared libraries: 
libldap-2.3.so.0: cannot open shared object file: No such file or directory

$ldd /usr/pkg/libexec/sendmail/sendmail
        libssl.so.0.9.7 => /usr/lib/libssl.so.0.9.7 (0x4003a000)
        libsasl2.so.2 => /usr/local/lib/libsasl2.so.2 (0x40184000)
        libldap-2.3.so.0 => not found
        liblber-2.3.so.0 => not found
        libdb4-4.4.so.4 => not found
        ...

Looking in work/.work.log, I found no -R options to the linker or compiler.
>How-To-Repeat:
Install newer versions of OpenLDAP, BerkeleyDB, or other libraries onto a Linux 
system from pkgsrc, then install Sendmail from pkgsrc with the appropriate 
options enabled so that it depends on them and see that the generated binaries 
cannot find the libraries from pkgsrc unless /usr/pkg/lib is added to 
/etc/ld.so.conf and /sbin/ldconfig is re-ran.
>Fix:
A work-around on Linux is to add /usr/pkg/lib to /etc/ld.so.conf and run 
/sbin/ldconfig to update the library cache.  This causes sendmail from pkgsrc 
to find the appropriate libraries, but, of course, causes a lot of the base 
system programs to change to the libraries from pkgsrc.  The correct course of 
action is to have sendmail linked with the appropriate -R option.
