Hi,
it is necessary because the log files are named like  
$(THISAPP)-$(VER).  When in Ncat and Nmap
$(THISAPP)-$(VER) = nmap-7.12 is or the strings in both lfs files  
(ncat and nmap ) are the same, the log files are named identically. So  
the log file of the nmap package overrides the log file of the ncat  
package  .This should not happen.
The easiest solution till now was to change the name of the source  
tarball to ncat.

Or a way which I discover just now. Maybe it is a solution to change this to

VER        = 7.12

THISAPP    = ncat-$(VER)
DL_FILE    = nmap-$(VER).tar.bz2
DL_FROM  = $(URL_IPFIRE)
DIR_APP    = $(DIR_SRC)/nmap-$(VER)
TARGET     = $(DIR_INFO)/nmap-$(VER)
I will try this solution and if it works will send a new patch set.  
This solution is much more elegant :-).

Regards Jonatan
