psicode

Hi,
my OS is archlinux that is based on debian. However, when I type "make",
fiveth step of the instalation manual, the system return the errors below:

/usr/local/src/psi3/src/lib/libutil/stl_string.cc:239: error: ‘fprintf’
was not declared in this scope
/usr/local/src/psi3/src/lib/libutil/stl_string.cc:240: error: ‘fflush’
was not declared in this scope
/usr/local/src/psi3/src/lib/libutil/stl_string.cc: In function ‘void
psi::print_error(const char*, const char*, int, int)’:

How can I to resolve this problem?

Thanks
