[Cryptography Team] Issues: Trying to build the RS vm with the mvm script...

I am trying to build the vm with RS external plugins I generated. I am getting some pushback:

rabbit@ganymede:~/vm-dev/opensmalltalk-vm/build.linux64x64/squeak.cog.spur/build$ ./mvm clean? y checking for gcc... clang checking whether the C compiler works... no configure: error: in `/home/rabbit/vm-dev/opensmalltalk-vm/build.linux64x64/squeak.cog.spur/build': configure: error: C compiler cannot create executables See `config.log' for more details

How could I resolve this issue? I have the latest gcc, I think:

rabbit@ganymede:~/vm-dev/opensmalltalk-vm/build.linux64x64/squeak.cog.spur/build$ gcc --version gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0

I appreciate!
