installXLSXsupport() error

Hi!

Until now I've survive exporting my spreadsheets to CSV files, but this process is a error-prone as it is by no means easy to keep track of updated releases. Some weeks ago a new thread here talked about reading XLSX files by using gdata(): it would be really great to be able to get this working here, but I'm running into some trouble. Gdata works fine to read XLS format, but I'm not able to get XLSX support. Please, check this outputs. First of all: sessionInfo()...

I've read ?installXLSXsupport and I think I've correctly installed Compress::Raw::Zlib and Spreadsheet::XLSX from terminal (by using sudo perl -MCPAN -e 'install Bundle::Name'). I've even tried with a different Perl flavour, ActivePerl, but got a different set of errors. I'm afraid I'll make my installation an awfull mess if I keep trying to get an answer on my own! Please, could you help me? Do you know where am I wrong? How could I get XLSX support working in my MacBook Pro running Mac OS X 10.5.8?

Thank you so much for your help,

Ricardo
