[Bioc-devel] Error in .get_entry_index(name, stop_if_missing)

Hi I had the following error while checking the package https://github.com/xyang2uchicago/BioTIP

base::assign(".ptime", proc.time(), pos = "CheckExEnv")
### Name: getCluster_methods
### Title: Clustering Network Nodes
### Aliases: getCluster_methods

### ** Examples

test = list('state1' = matrix(sample(1:10,6),3,3),'state2' =

+ matrix(sample(1:10,6),3,3),'state3' = matrix(sample(1:10,6),3,3))

#assign colnames and rownames to the matrix

for(i in names(test)){

+ colnames(test[[i]]) = 1:3
+ row.names(test[[i]]) = 1:3}

#using 'rw' or 'natural' method
igraphL <- getNetwork(test, fdr=1)

[1] "state1:3 nodes"
[1] "state2:3 nodes"
[1] "state3:3 nodes"

#[1] "state1:3 nodes"
#[1] "state2:3 nodes"
#[1] "state3:3 nodes"

cl <- getCluster_methods(igraphL)

#using 'km', 'pam' or 'hcm'
cl <- getCluster_methods(test, method = 'pam', cutoff=2)

Error in .get_entry_index(name, stop_if_missing) :
  Entry TSDistances not in registry.
Calls: getCluster_methods ... TSDatabaseDistances -> dist -> <Anonymous> -> f -> .get_entry_index
Execution halted

It seems the problem is because the required library 'TSdist' not load successfully. However, import(TSdist) is written in both DESCRIPTION and NAMESPACE.
