title: Error: Maximal number of DLLs reached
body: <p>I'm writing an R package which depends upon many other packages. When I load too many packages into the session I frequently got this error:</p>
  
  <pre><code>Error in dyn.load(file, DLLpath = DLLpath, ...) : 
    unable to load shared object '/Library/Frameworks/R.framework/Versions/3.2/Resources/library/proxy/libs/proxy.so':
    `maximal number of DLLs reached...
  </code></pre>
  
  <p>This post <a href="https://stackoverflow.com/questions/24832030/exceeded-maximum-number-of-dlls-in-r">Exceeded maximum number of DLLs in R</a> pointed out that the issue is with the Rdynload.c of the base R code:
  <code>#define MAX_NUM_DLLS 100</code></p>
  
  <p>Is there any way to bypass this issue except modifying and building from source? </p>
