Version 1.5 installed by Alfonso Dec. 2016 in
/temp4/bio/APBS/APBS-1.5/bin/apbs
You need to set
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/temp4/bio/APBS/APBS-1.5/lib
to run the program; Otherwise you get
apbs: error while loading shared libraries: libmaloc.so.1: cannot open shared object file: No such file or directory
