title: Error: in dyn.load(file, DLLpath = DLLpath, ...): unable to load shared object
body: <p>I'm trying to load a package I have installed via Bioconductor (using BiocLite()) as I have done with many other similar packages from the same source. However I get this error:</p>
  
  <pre><code>[Error: package or namespace load failed for 'GenomicFeatures' in dyn.load(file, DLLpath = DLLpath, ...):
   unable to load shared object '/Users/mario/Library/R/3.4/library/rtracklayer/libs/rtracklayer.so':
  
  dlopen(/Users/mario/Library/R/3.4/library/rtracklayer/libs/rtracklayer.so, 6): Library not loaded: /usr/local/opt/openssl/lib/libssl.1.0.0.dylib
    Referenced from: /Users/mario/Library/R/3.4/library/rtracklayer/libs/rtracklayer.so
  
    Reason: image not found]
  </code></pre>
  
  <p>If I try to install and load library <code>rtracklayer</code> I get the same message</p>
  
  <p>I've tried reading to answers for similar questions on the site but I still can't figure out what the problem is.</p>
  
  <p>Any suggestions?</p>
