Okay, thank you for responding.
you are absolutely razon (. I modified file src/package.h adapting to 
the needs to handle the extension (. ikg) as follows.

#define SLAPT_PKG_PARSE_REGEX "(.*{1,})\\-(.*[\\-].*[\\-].*).ikg[ ]{0,}$"
#define SLAPT_PKG_NAME_PATTERN "^PACKAGE NAME:[ 
]{1,}(.*{1,})\\-(.*[\\-].*[\\-].*)(.ikg)[ ]{0,}$"
#define SLAPT_MD5SUM_REGEX "([a-zA-Z0-9]{1,})[ 
]{1,}([a-zA-Z0-9\\/._\\-]{1,})\\/(.*{1,})\\-(.*[\\-].*[\\-].*).ikg$"

But unfortunately for me, the situation is persistent
looking a little code in the file src/packages.c, find that my problem 
is generated by the function "slapt_verify_downloaded_pkg" in the variable
"file_size = slapt_get_pkg_file_size(global_config,pkg)" around the line 
2201 if any comment on this variable besides the line 2193

package.c - line 
2193----------------------------------------------------------
/*size_t file_size = 0;*/
-------------------------------------------------------------------------------------------

package.c - line 2201-2204--------------------------------------------------
  /*
  file_size = slapt_get_pkg_file_size(global_config,pkg);
  if ((unsigned int)(file_size/1024) != pkg->size_c) {
    return SLAPT_DOWNLOAD_INCOMPLETE;
  }
  */
-------------------------------------------------------------------------------------------

The code compiles and the program does not give more problems; But I 
suppose this is not the best way to solve the problem
