It's not Apache httpd that needs to be compiled for FIPS, it's
OpenSSL. So if you have a FIPS-capable OpenSSL library, you should be
okay.

Building a FIPS-capable OpenSSL is possible, but requires some steps
on top of the usual OpenSSL build process:

http://openssl.org/docs/fips.html

Unless you have some regulatory requirement to use FIPS, I wouldn't
bother with the whole mess. FIPS does two things: (1) validates the
library on startup to ensure it hasn't been tampered with (which I
suppose is good) and (2) mandates a specific set of hashes, ciphers,
etc. (bad). The reason #2 is bad is because the set of ciphers
required by FIPS includes known weak ciphers, and probably also
contains unknown weak ciphers, too.

AFAICR, FIPS also will not allow you to use additional ciphers on top
of the FIPS requirements, so you aren't allowed to use the latest and
greatest ciphers recommended by security experts.

(Finally, it's unclear whether or not it's actually possible to
produce a FIPS-compliant implementation *at all*, so the whole thing
is a farce, anyway.)

So, unless you have a specific and unyielding requirement to use a
FIPS-compliant library, save your time and just configure your
non-FIPS-compliant server in a sane way and you'll be fine.
