I take it that zdplaskin is the plasma kinetics program? If so, have you
followed all the instructions found in the following link?
The error you got "undefined reference to 'zdplaskin_bolsig_initcondition"
probably means that there's some problem finding the lib. Unfortunately,
this is as far as I can go without more info from you, ie the file you
tried to compile, the makefile or script you used etc.
According to this:
g95 hasn't been officially tested by the developers, so perhaps you could
try one of the other compilers if all fails :(
