Overriding a bad checksum

[Marshall Pierce]

A handful of packages I'm trying to use have invalid md5 checksums on 
repo1.maven.org, e.g.:

[ivy:resolve] 	problem while downloading module descriptor: 
http://repo1.maven.org/maven2/org/apache/ws/commons/axiom/axiom-dom/1.2.7/axiom-dom-1.2.7.pom: 
invalid md5: expected=\7986af8834017fafae425331b9d2dc6f 
computed=7986af8834017fafae425331b9d2dc6f (799ms)

When I check the .md5 file 
(http://repo1.maven.org/maven2/org/apache/ws/commons/axiom/axiom-dom/1.2.7/axiom-dom-1.2.7.jar.md5), 
sure enough, there is a spurious \ at the beginning. Clearly, the file 
is actually valid, since the computed md5 would be the same as the 
expected md5 if it didn't have the \ in front. How can I get the 
resolver to ignore the "bad" md5?

Thanks,
