We wrote a tool for extracting mel-generalized cepstral coefficients from spectral envelop.
Mel-generalized cepstral analysis includes LPC, mel-LPC, cepstral, and mel-cepstral analysis as its special case, 
so this tool can be used to extract mel-cepstral coefficients or mel-LSP.
This tool may be included in the next SPTK release.
