If a randomly clobbered together and unvetted system is compliant, but bcrypt isn't, that just goes to show how little FIPS140-2 compliance actually means. (as if everybody didn't already know it's worthless)
Nonetheless, some projects mandate use of FIPS 140-2 hashing algorithms, and afaik bcrypt is not one. So if you find yourself on such a project, bcrypt is not an option on the table.
