There's a bug in their release:

marto@Shemp:~/code/what/ViewBS-0.1.7$ ls
conda  doc               INSTALL     license.txt  test.py
cpanm  environment.yaml  INSTALL.pl  README.md    ViewBS
data   image             lib         Rplots.pdf   ViewBSdocker
[download]

And their INSTALL.pl looks for cpanm in:

## Check cpanm 
my $dir = dirname(abs_path $0);
my $CPANM = "$dir/ext_tools/cpanm";
[download]

Note the extra ext_tools directory. So when you run INSTALL.pl as directed by the docs, you get the error:

marto@Shemp:~/code/what/ViewBS-0.1.7$ perl INSTALL.pl 
PASSED: Perl version(5.026001 >= 5.14.4).
Error: cpanm not found in /home/marto/code/what/ViewBS-0.1.7. Please c
+heck.

A quick fix would be to create a directory called ext_tools, and move cpanm in there, then continue the process:

marto@Shemp:~/code/what/ViewBS-0.1.7$ mkdir ext_tools
marto@Shemp:~/code/what/ViewBS-0.1.7$ mv cpanm ext_tools/
marto@Shemp:~/code/what/ViewBS-0.1.7$ perl INSTALL.pl
[download]

The previous release had this directory, and cpanm was the only thing in it. I've raised the issue over at the github repo.

Update: Well, the owner fixed the issue very quickly. The system works :)
