System details: BusyBox v1.18.5 (2011-07-13 22:22:30 UTC) multi-call binary. Linux box 2.6.33.3-tinycore #2012 SMP Wed May 12 17:05:42 EEST 2010 i686 i686 i386 GNU/Linux PS: This bug is probably the root of the problems in installing lilypond reported here: http://comments.gmane.org/gmane.comp.gnu.lilypond.general/63319 http://www.murga-linux.com/puppy/viewtopic.php?t=66365&sid=6e63c0bb8c0297cf6231218ed3a7394e and elsewhere. Since this works exactly up to lilypond version 2.13.41, I expect some bug triggering threshold laying between 7747 and 8200 (as above).
