IF I understand: no. Python is not a standard part of some UNIX packages, you have to add it on later. Solaris 10 is an example.

And if python is out there already it may well be 2.7. FFT algorithms in perl are absolutely all over the place on the net. You could certainly find one to use close to as is.

A google for 'fft perl example' finds lots of code. perl has had it in MATH:: since 2002.
Note: there are linux distributions like DSL that have almost nothing extra, just bash and gcc and c runtime. No perl, no python.

IMO your question may not be so easy to answer well. Your perl assumption has problems.

You can do some math in shell only -

SYNOPSIS

       pycentral [-h] [-v] <cmd> [<cmd options>] [<args>]

DESCRIPTION

       pycentral
	provides support for installing python modules independent
	of the current installed Python version and handling
	byte-compilation and -removal tasks in installation scripts.

       -v, --version
	      Limit the output to the version numbers of the python versions.

       -h, --help
	      Print a help text.

       pycentral has the following sub commands. For fine grained help, call: pycentral <cmd>.

       bccompile
	      Byte compile .py files in a package.

       bcremove
	      Remove the byte compiled .py files.

       list   List all managed files.

       pkginstall
	      Make a package available for all supported runtimes.

       pkgprepare
	      Prepare a package for all supported runtimes.

       pkgremove
	      Remove a package installed for all supported runtimes.

       pkglist
	      List pycentral-managed files of a package for all supported runtimes.

	      move files to pycentral locaation, variable substitutions (called by dh_pycentral).

       pycentraldir <package>
	      Show the installation directory used by pycentral for <package>.

       showdefault
	      Show default python version number. Deprecated, use pyversions(1)

       showsupported
	      Show the supported python versions. Deprecated, use pyversions(1)

       showversions
	      Show version numbers of supported python versions.  Deprecated, use pyversions(1) dh_pycentral, should not be called directly).

       version
	      Show the pycentral version.

FILES

       /etc/python/debian_config   is	searched   for	 the   attribute   overwrite-local.    If   set   to   1,   or	True,  existing  files	in
       /usr/lib/pythonX.Y/*-packages are overwritten with symbolic links to the pycentral install area. The default is to abort  the  installation
       of  a  package,	when files already exist. This behaviour may be useful, when python libraries were manually installed into this directory.
       The attribute byte-compile can be set to a comma separated list of the values standard and optimze to indicate how files  should  be  byte-
       compiled.
