I have written a sweave document that could be used as a vignette but which I currently 'build' separately because it makes use of local installations of the two external applications. Is there any way that I could get this package into Bioconductor with a vignette that won't build until the user installs these applications? Or should I just sent it to CRAN?

You might just add an eval=false to the appropriate chunks.  That may
mean that you need to include some small example MUSCLE and BLAST
outputs so that the rest of your code can work from that instead.
