qdap installation problem

Hi,
I'm trying to install "qdap" package for text mining and there seems to be an error with its loading.
When I download the package, I get this message:

There are binary versions available but the source versions are later:
binary source needs_compilation
openNLP 0.2-6 0.2-7 FALSE
stringdist 0.9.5.3 0.9.5.5 TRUE

Do you want to install from sources the package which needs compilation? (Yes/no/cancel)

Whether I choose yes or no, I get this message:
ERROR: lazy loading failed for package ‘openNLP’

  • removing ‘/Library/Frameworks/R.framework/Versions/3.6/Resources/library/openNLP’
    Warning in install.packages :
    installation of package ‘openNLP’ had non-zero exit status

The downloaded source packages are in
‘/private/var/folders/9l/31q8n1y90z5675pygx688m2c0000gn/T/RtmpQbNBA0/downloaded_packages’

None of the qdap function works and when I try to load the package, I get this:
Error: package or namespace load failed for ‘qdap’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
there is no package called ‘openNLP’

If anyone could help, I'd be grateful - I'm just starting with R and I've been stuck on that for quite a while.

I think you are omitting the important parts of the error message, what is the whole message you get if you try to install the missing dependency?

install.packages("openNLP")

Here's the whole thing:

> install.packages("openNLP")

  There is a binary version available but the source version is later:
        binary source needs_compilation
openNLP  0.2-6  0.2-7             FALSE

This is the key part, R is not being able to find a Java installation in your system. Do you have Java installed in your system? if so, it matches the R installation architecture (i.e. 32 or 64 bits)?

That's the issue, I have installed Java, JDK and Xcode and I'm running all on 64-bit and R on 64-bit as well.
