No additional output is produced when I changed both of the eval($fcn) commands near 774.

One thing to note is that to get this to actually export the functions, I had to copy the export block from the SHA.pm module like below, otherwise, I would get errors when trying to import the function names. 
@EXPORT_OK = qw(
    hmac_sha1       hmac_sha1_base64        hmac_sha1_hex
    hmac_sha224     hmac_sha224_base64      hmac_sha224_hex
    hmac_sha256     hmac_sha256_base64      hmac_sha256_hex
    hmac_sha384     hmac_sha384_base64      hmac_sha384_hex
    hmac_sha512     hmac_sha512_base64      hmac_sha512_hex
    sha1            sha1_base64             sha1_hex
    sha224          sha224_base64           sha224_hex
    sha256          sha256_base64           sha256_hex
    sha384          sha384_base64           sha384_hex
    sha512          sha512_base64           sha512_hex);

With this block commented out, printing out the export list gives no output.
