[BioC] A circular problem: re-annotation of custom PM only probes

I would like to re-annotate probes for a custom PM-only chip. I tried using 
altcdfenvs, but discovered that I first needed a make a probes database for 
my CDF library. To do this I tried using makeProbePackage, only to discover 
that the package matchprobes does not accept that my probes are PM-only. 
Like several people before me, I get the error message

Error in rep(NA, max(pm1, mm1, pm2, mm2)) : invalid 'times' argument

THere has been mention that going back to an older version of matchprobes 
will overcome this PM-only problem. Does anyone know of other workarounds?

I am using the most up-to-date version of R and its packages.
