TGICL installation

[likebiology]

Hi Everybody,

I de novo assembled a transcriptome and want to cluster it using TGICL. I download TGICL-2.1.tar.gz and decompressed it.
I typed tgicl -h, the error is :
Can't locate TGI/Mailer.pm in @INC (@INC contains: /home/cishu/Download/TGICL-2.1/bin /etc/perl /usr/local/lib/perl/5.10.1 /usr/local/share/perl/5.10.1 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl .) at /home/cishu/Download/TGICL-2.1/bin/tgicl line 9.
BEGIN failed--compilation aborted at /home/cishu/Download/TGICL-2.1/bin/tgicl line 9.

According to other post:http://seqanswers.com/forums/showthread.php?t=15660,
I used : export PERL5LIB=/home/cishu/Download/TGICL-2.1/lib/TGI. I typed tgicl again, then another error comes:

Could anybody show me to to fix it? Thank you!
