[Spacewalk-list] PyYAML problem during upgrade 1.3 to 1.4

[rob morrien]

Hello during the upgrade from spacewalk 1.3 to 1.4

i get the a second error :

--> Finished Dependency Resolution
PyYAML-3.08-4.el5.i386 from installed has depsolving problems
  --> Missing Dependency: libyaml-0.so.1 is needed by package
PyYAML-3.08-4.el5.i386 (installed)
Error: Missing Dependency: libyaml-0.so.1 is needed by package
PyYAML-3.08-4.el5.i386 (installed)


if i do :

rpm -qa | grep PyYAML
PyYAML-3.08-4.el5


that means PyYAML is installes , so i don't understand the dependency problem

who can help me to fix this problem.
