As far as I can see, the current version of dvtm does not work properly with programs such as htop etc.
To reproduce:
```
$ guix package -i dvtm
$ dvtm
$ htop
```
It only worked properly once I added something like:
`export TERMINFO_DIRS="/home/jelle/.guix-profile/share/terminfo"`.
Would a proper fix be to simply add a native-search-path declaration to the dvtm package? If so, I can prepare a patch this weekend.
