Correct, .sl files are really NMXLs, and .a files are really NMRLs.

API.sl is an NMXL with external references to the LDAP C SDK.

You need to do either of the following:

1) Recreate API.sl but statically link it with the LDAP C SDK .a NMRL.

OR

2) Relink PERL.PUB.PERL to include the LDAP C SDK .sl NMXL in the
appropriate place within the XL list.  :LINKEDIT ALTPROG XL= can do that.

I've never used the LDAP/iX C SDK, nor have I ever used any of the Perl LDAP
extensions, but I'm pretty sure this is your problem.
