 #getting pecl install intl to work:
 
 #if you get compile errors like this: 
 #error: ‘UChar’ does not name a type
 #then you may need to remove libicu and all dependencies, forcibly download libicu55 and icu-devtools version 55
 #compile intl, then update back to 60.2 and reinstall all removed dependencies later
 #general process:
 
 apt-get remove -y icu-devtools libharfbuzz-dev libicu-dev libicu-le-hb-dev libmagickcore-6.q16-dev libmagickwand-6.q16-dev libmagickwand-dev libxml2-dev libxslt1-dev
