[Apbs-users] Re: mpi

[William S. <wg...@ch...>]

Hi Malcolm:

It turns out with a separate build of lammpi it all works as  
advertised, so the
problem is with the package that currently exists in the fink package  
management
system.  I've got the maintainer working on the problem too, so it  
should be sorted
out.  The good news is that there is NOT a problem on the apbs side  
of things.  For
some reason, if lamd is built against dynamic rather than static  
libraries, it gives this
error, and this is apparently a known issue (thanks to your google  
suggestion, it is now
known to me, too).

(Passwordless ssh works fine, and I was also having the problem with  
just localhost.)

Many thanks, and also, sorry to bother you with a problem that it  
turns out had nothing
to do with apbs.

Bill
