how to make example-package run correct

[xuhaida]

Hello,

I am planning to  port sci-doe to octave, and clone the example-package 
from octave-forge . To test the package, I use "make dist" in the 
plain-package directory, but see the following error:

rm -f -r "target/example-package-1.2.0"
cd "target/example-package-1.2.0/src" && ./bootstrap && rm -f -r 
"autom4te.cache"
/bin/sh: 1: cd: can't cd to target/example-package-1.2.0/src
make: *** [Makefile:117：target/example-package-1.2.0] 错误 2

 I check the directory and can't see the target directory.  So I clone 
the dataframe package, use the same command, but see the target 
directory. Can some one tell me how to  run example-package  correctly?
