Perhaps something like

pkgEnv = getNamespace("MyPackage")
attach(pkgEnv)

You might also be interested in assignInNamespace -- perhaps you can
add you function to the package's name space and then call it using
:::.

Be warned, this is the wrong way to solve a long-term problem.  Bad
things will happen and nobody will feel sorry for you.
