oops, forgot -u (added it to cvsrc :) )

DragonFly-HEAD (with default CCVER, that is gcc41):
# cc -v
Using built-in specs.
Configured with: DragonFly/i386 system compiler
Thread model: posix
gcc version 4.1.2 (DragonFly)

Dies during configure stage since it can't find f77 when using gcc41:
checking for i386-pc-dragonfly-g77... (cached) f77
checking whether we are using the GNU Fortran 77 compiler... (cached) no
checking whether f77 accepts -g... (cached) no
checking how to get verbose linking output from f77... configure: WARNING:
compilation failed

checking for Fortran 77 libraries of f77...
checking for dummy main to link with Fortran 77 libraries... none
checking for Fortran 77 name-mangling scheme... configure: error: cannot
compile a simple Fortran program
See `config.log' for more details.
*** Error code 1

well adding "PKGSRC_COMPILER= f2c gcc" in my mk.conf installs f2c and makes
fftw compilable with gcc41 ... but im not sure if it should be the default
since gcc34 that is also included in the system also has a fortran compiler.
