Hi,
First, this is really more of a question for R-package-devel:
https://stat.ethz.ch/mailman/listinfo/r-package-devel)
not R-Help. :-)
Starting with R 3.0.0 (April of 2013), NAMESPACE files for packages were mandatory, whereas before that, they were optional. That is the primary issue.
If the original package author/maintainer has ceased to update the package, thus not available to assist, the primary documentation that you would need is in the R-Exts manual, specifically:
https://cran.r-project.org/doc/manuals/r-devel/R-exts.html#Package-namespaces
Depending upon the residual errors that you are getting, if you can provide additional details so that folks can provide better assistance, subscribe to and post to R-package-devel for further discussion.
Regards,
Marc Schwartz
