After yet another debug session on IRC about failure to use qemu because yajl-devel wasn't installed, I came up with these patches. The first is just preparation (no change to generated code); and with the second, I validated that uninstalling yajl-devel and then trying to configure once again gives me the desired: checking for yajl_tree_parse in -lyajl... no configure: error: You must install the libyajl library & headers to compile libvirt [I can't claim build-breaker or trivial rule for either of these patches, but as I am also the autoconf guru around here, I won't be surprised if the extent of other's reviews is "yep, I installed it and it did what you said"...] And yes, I tested on RHEL 5 that it still works with autoconf 2.59.
