Dir.chdir, preferably with a block.
e.g:
irb(main):001:0> Dir.pwd
=> "/Users/logan/Projects/Ruby Experiments"
irb(main):002:0> Dir.chdir("/") { puts Dir.pwd; `ls` }
/
=> "Applications\nApplications (Mac OS 9)\nDesktop DB\nDesktop DF 
\nDesktop Folder\nDeveloper\nLibrary\nNetwork\nPrevious Systems 
\nSystem\nSystem Folder\nTheVolumeSettingsFolder\nUser Guides And  
Information\nUsers\nVolumes\nautomount\nbin\ncores\ndev\netc\nmach 
\nmach.sym\nmach_kernel\nprivate\nsbin\nsw\ntmp\nusr\nvar\n"
irb(main):003:0> Dir.pwd
=> "/Users/logan/Projects/Ruby Experiments"

So in your case you would use:
cvs_output = Dir.chdir("somewhere") {  `cvs update` }
