You have to supply "PC" as a precompilation option. 
Please follow the instructions THAT REFER TO THE 
VERSION OF THE CODE THAT YOU ARE USING, 
in particular those contained in the sample makefiles
(install/Make.pc_ifc) and in the manual (pwdocs/manual.tex)

this problem has been discussed several times in the
mailing list. You have to 
- link to fftw library, and
- compile with the appropriate number of underscores,
  as explained in the manual
