Only thing I can think of that would have otherwise broke EGC for me is a "sudo yum update" from the other day as yum history shows nothing else.
That being said, if EGC is so closely based off of BTC, why is it now broken ?
I know that question might not be easily answered but this is honestly the most frustrating thing I've ran into since I had to build my own QT since a linux one is not offered where most all other coins have one built for end use already.
[amcnamara@Crypto-Online ~]$ /home/amcnamara/Desktop/EverGreenCoin-Qt -testnet=0 -regtest=0
/home/amcnamara/Desktop/EverGreenCoin-Qt: error while loading shared libraries: libboost_system.so.1.57.0: cannot open shared object file: No such file or directory
[amcnamara@Crypto-Online ~]$
What OS is running on that system. Use of yum makes it look like an older Fedora/RHEL based system.
That error makes it look like either a significant update to the boost libraries happened or they got removed. Maybe try looking to see what boost packages are currently installed.
