title: Unable to install pal2nal package in anaconda
body: <p>I am new here and also just learning how to work in anaconda, so I would like to ask for help. I need some packages installed to be able to run my sequence analysis and calculate dN/dS ratio. For that I need paml, clustal omega, prank, blast and pal2nal packages to be installed. I'm working in Windows 10 (unfortunately, but no other way - working laptop).</p>
  <p>I have been trying to install pal2nal package in anaconda using conda, bioconda, pip commands and I always get the same error.</p>
  <p>My tries:  conda install -c bioconda pal2nal, conda install -c anaconda pal2nal, conda install pal2nal, pip install pal2nal (it doesn't exist among python packages) and I even tried to create a new environment and install it there but no luck. It's the same with the rest of the packages.</p>
  <p>The message what I always get is:
  Collecting package metadata (current_repodata.json): done
  Solving environment: failed with initial frozen solve. Retrying with flexible solve.
  Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

  <p>Does anyone know why I always get this error and maybe what to do to be able to install these packages?</p>
  <p>Thank you very much for help!!</p>
