R help - Jun 2006 - fclustIndex(package e1071) error: LaPack Routine dgesv

Dear colleagues:

Despite my best efforts, I have not been able to understand/overcome  
an error message I received while running the fclustIndex command in  
package e1071, which produces validity measures for the fuzzy c-means  
clustering algorithm.  I am relatively new to R-- and still depend  
heavily on Rcmdr-- and so I apologize in advance if there is an  
obvious answer to my question:

My code is as follows:

library(e1071)
Dataset <- read.dta("/Users/chris/Desktop/Fuzzy Cluster.dta",  
convert.dates=TRUE, convert.factors=TRUE, missing.type=TRUE,  
convert.underscore=TRUE, warn.missing.labels=TRUE)
row.names(Dataset) <- as.character(Dataset$cntry)
Dataset$cntry <- NULL
cl <- cmeans(Dataset, 4, 20, verbose=TRUE, method="cmeans")
resultindexes <- fclustIndex(cl, Dataset, index= "all")
resultindexes

I am receiving the following error message:

ERROR:  Lapack routine dgesv

I have tried running the example for fclustIndex and it works fine.   
The code above is based on the example from the manual (below).  I  
also checked that I have the latest version installed.  I have also  
had no trouble running similar commands from other packages which  
leads me to believe that everything is installed/compiled properly--  
where have I gone wrong?

The description of fclustIndex in the e1071 .pdf is available via the  
following link:

I thank you in advance for your time and help.

Sincerely,
Christopher Bail
