Are you talking about linking with "-static" or just with  
libibverbs.a?  I'm talking about linking with -static, which has more  
requirements than just linking libibverbs.a and <your_driver.a>.  I  
don't see mention of that in the thread that you cite on the HowToFAQ.

There are issues with deep linker voodoo that prevent -static from  
working properly that Roland just fixed -- he had to change the order  
of loading up the plugins so that you wouldn't get multiple versions  
of system libraries loaded into the same process, such as one  
statically linked in and one dynamically linked in that was pulled in  
by an implicit linker dependency from the DSO that was dlopen()'ed.   
This causes Bad Things to happen; lions, tigers, and bears.

Roland -- can you explain what you did?  I think I could explain it,  
but better to come from the guy who did it so that the details will  
be right.
