running Make_toolKit.ipl fails

System

my teamate wantd to add new item the action Menu so he did the following as the pdf guide says:
-----------------START OF THE pdf---------------------
Alternatively, you can apply all the sample changes at once by appending the sample toolkit
to the end of the toolkit list in:
iw-home/local/config/lib/content_center/toolkits.xml
This file contains:










path="C:\iw-home/private/lib/content_center/teamsite_admin.tk.war"/>




path="C:\iw-home/local/config/lib/content_center/customer_out/customer.tk.war"/>

Add the following element just before the closing element :

path="iw-home/local/config/lib/content_center/customer_samples_out/customer_samples.tk.war"/>
substituting for iw-home appropriately, and save this file. Change directory to:
iw-home/local/config/lib/content_center/customer_samples_src

and then rebuild the web application normally by issuing:
iw-home/iw-perl/bin/iwperl iw-home/bin/make_toolkit.ipl

-----------------END OF THE pdf--------------------------
so the last step is the problem, everytime we put that command it says:
###
BUILD FAILED. problem creating war: there is no enough space on the disk (and the archive is probably corrupt but i could not delete it)
###

so if any body has any suggestions about fixin the disk space and rrunning "make_toolkit.ipl"?
