[igraph] Compile failure with last two nightly builds of igraph C core -- missing header files

[Tony]

On a 64-bit Ubuntu box (kernel 2.6.32-28-generic), the last two
nightly builds (0.6-2321-2011206 and 0.6-2326-20110207) hit compile
failures deep into the compile/build phase.  Specifically, when
compiling f2c/iio.c, I see errors about fio.h and fmt.h (not such file
or directory) and resulting undeclared functions in iio.c

Thanks for any assistance.
