Looked up MMA.* in /usr/local and deleted whatever directories started with IPC (module is IPC::MMA ie IPC/MMA). Made no difference. My ll command shows .files which I think are what Unix would call a hidden file. Not sure what a system file would be... is that a unix or windows concept?
<br Looked up posts for the specific error message and no answerer ever said "this message happens when (entity) compares the (something) to the bootstrap or version in the .pm file". Nothing like that anywhere on the Net!

Did I mention this is an xs module? in 'perlxs' I find the following:
The VERSIONCHECK: Keyword
The VERSIONCHECK: keyword corresponds to xsubpp's -versioncheck and -n
+oversioncheck options. This keyword overrides the command line option
+s. Version checking is enabled by default. When version checking is e
+nabled the XS module will attempt to verify that its version matches 
+the version of the PM module.
To enable version checking:
    VERSIONCHECK: ENABLE
To disable version checking:
    VERSIONCHECK: DISABLE

I guess my Q devolves into "where does the XS module get/determine 'its' version to match against the .pm version which is the thing that has gone up to 0.5.1?"
