I rebuilt libxml, xmlsec, and libxslt to the latest and I get an x509 error
for some reason. Any ideas on this?
libxml version: 2.7.7
xmlsec version: 1.2.16
libxslt version: 1.1.26
func=xmlSecOpenSSLX509StoreInitialize:file=x509vfy.c:line=657:obj=x509-store:subj=X509_LOOKUP_add_dir:error=4:crypto
library function failed:

library function failed:
