If you have RSA private key components you may use OpenSSL API (RSA/BIGNUM) or you may convert this to ASN1 private key structure (DER format) and next to PEM format. You may use "openssl asn1parse" to display or convert. Some time ago I sent small perl script to do something like that. (conersion from BIND to DER fromat). Hope this helps.
