Pkg install error internal compiler error

Hi to the community,
I am having problems running the following command: >> pkg install -forge io statistics control struct optim“.

My device is a MacBook Pro running Catalina macOS 10.15.7 and I have GNU Octave, version 6.2.0 installed.

My goal is to get Octave running to be able to use Dynare. First, I updated Homebrew. Then, I installed Octave using Homebrew via the Terminal which did not result in any errors. Then, I run Octave via the command „octave —gui“ and it opens just fine. In order to use Dynare I need to install the statistics package executing the following command ">> pkg install -forge io statistics control struct optim“. 
The resulting error is the following: 

>> pkg install -forge io statistics control struct optim

warning: LFLAGS is deprecated and will be removed in a future version of Octave, use LDFLAGS instead
