How would I find out if libdl.so.2 have _dl_lookup_symbol included? What is nm? 
Forgive me, I am not a programmer anymore. I last programmed in COBOL
days. I am the systems person and we upgraded to CentOS from RHAS21
and now the programmer can't compile. He gave it to me to figure it
out. I understand makefiles, et al to a point that I have to compile
drivers and such, but my expertise is limited in this area. But always
willing to learn a new trick.
