Thanks for taking over an orphaned package. Not an easy task!

I think that dnapath is calling `gtools::permutations` from
`dnapath.R` around lines 339-343 [1], not `gtools::permute`.
Changes to the file `combinations.R` in `gtools` where `permutations`
resides were made in June 2021 [2].

I could not find an obvious place where the join above is happening in
the vignette, unfortunately, so I can't be of more help than just
pointing you in a different direction.
