The only thing I can think of that would generate such error messages
is if your compiler installation is incomplete.
Does your machine in fact have a dirent.h installed?
(normally in /usr/include/dirent.h and/or in /usr/include/sys/dirent.h)
Are you able to compile other packages besides gnuplot?

This again points to a compiler problem.
Do you in fact have gcc installed?
What do you get as output from
   gcc -v
