 Did a rebuild of the old trusty avr-gcc-4.3.4 toolchain , with avr-libc-1.7.1 and avrdude-5.11 - avr-insight has switched from 6.8-1 to 6.8-1a
 
 Had to do a "kludge" in order to build avr-insight , ad the file is named 6.8-1a , but it extracts to 6.8-1 directory
 Run ./repack-insight.sh , before ./buildinsight.sh
 
 avr-libc has the patches applied , included in the zipfile.
 
 *** Also got rid of the dangerous rm -fr commands in the get-patches.sh script ***
 Hopefully it should not be "destructive" anymore 
 
 Added Core variable in package-versions , this indicates how many cores (cpu's) make should use  "make -j${Cores}"

 Only toolchain change is switch from insight6.8 to insight 6.8-1

 Switched to gcc-4.3.4 , Jörg did update the FreeBSD repos so it should perform like the WinAVR 2010 release.
 
 @08-mar-2010
 Switched to binutils 2.20
 
 @26-Jan-2010
 Avrdude 5.10 released , so build using that. All other , unchanged.
 
 @16-Jan-2010
 Avrdude 5.9 released , so build using that , instead of the 2 below patches.
 All other , unchanged
 
 @06-jan-2010
 Also apply this avrdude patch http://www.mail-archive.com/avrdude-dev@nongnu.org/msg01922.html
 to fix bug #27507. 
 Note... This patch isn't accepted upstream , but it is confirmed to fix a dragon isp programming crash
 
 
 @17-dec-2009   
 Rebuild avrdude 5.8 with the PDI patch from here
 http://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewtopic&p=637539#637539     
 
 
 
 This package will install avr-gcc-4.3.4 with binutils 2.20 and avr-libc 1.6.8.
 Plus  avr-insight 6.8  , avarice-2.10 and avrdude-5.10
 It will install in /usr/local/avr , and i honestly dont know what happens if this directory exists on install.
   
 A big thank you goes to the avr-gcc team , and Joerg Wunsch for making the FREE-BSD patches i use in the linux build,
 and for being a driving force in making/maintaining avr-libc.
 
 Thank you to Eric Weddington , for maintaining WinAVR , though it seems like WinAVR-2010 will be the last one.
  
 Also thanx to Ruud Vlaaming (FemtoOS) author , i snipped the GMP/MPFR GCC Inline trick from his toolchain.
