OS Update broke FR - rlm_exec-1.0.0.so not found

[Landon Cox]

Hi FR community,

I've been running FR on an updated (recently fully patched apps) SuSE  
9.2 (kernel 2.6.8-24-default)   I was successfully running an earlier  
version of FR and when I decided to do an update of FR through SuSE's  
online update, FR will no longer come up and fails with a dynamic  
link error:

radiusd:  entering modules setup
Module: Library search path is /usr/lib/freeradius
radiusd.conf[1367] Failed to link to module 'rlm_exec': /usr/lib/ 
freeradius/rlm_exec-1.0.0.so: cannot open shared object file: No such  
file or directory
radius2:/home/lcox # ls /usr/lib/freeradius/rlm_exec-1*
/usr/lib/freeradius/rlm_exec-1.0.0.la  /usr/lib/freeradius/ 
rlm_exec-1.0.0.so

As you can see, my /usr/lib/freeradius directory does have the .so  
file, but I can't tell from the output if rlm_exec is dependent upon  
some other file that is not found or the dynamic linker can't find  
rlm_exec-1.0.0.so.   So, that's one question - what is not being  
found?  Sounds obvious, except that I have the exact .so filename in  
the library search path.

SuSE Yast claims it has installed FR 1.0.0-5.6.   A radiusd -v produces:
radiusd: FreeRADIUS Version 1.0.0, for host , built on May 30 2005 at  
21:02:41
Copyright (C) 2000-2003 The FreeRADIUS server project.

I've seen numerous references to this exact linkage error on various  
freeradius lists as well as have seen it on lists for various  
architectures and *nix's, not just x86/SuSE Linux.  However, there is  
typically no response given to fix the problem except to rebuild FR  
with no shared libraries and even in those cases, the build often  
seems to break later leaving the admin stuck further down the line.

Is there a known solution to what seems like a relatively common  
problem of rlm_exec dynamic linkage issues?  What am I missing and  
what needs to be done to cause this to work with the shared .so lib  
file vs having to rebuild it with static libs?

Thanks in advance for any help or direction.
