I tried using the build script to install the dependencies and noticed two things which i fixed manually.
First of all the phonetisaurus download path from your github is not available anymore. I replaced it with the original. I hope there were no major changes in there?
Secondly while going through the steps of the bash file manually more precisely while doing ./configure for phonetisaurus i got asked to configure openfst with the --enable-static flag instead of the --disable-static. Only after doing so the configuration could find the openfst files even though included in the bash command.
Was the disable on purpose and is it connected to the phonetisaurus-2019 file from your git or is it a bug?
