I once ran into a similar problem in ghci when I had an unneccessary=20
"-lc" in the package configuration, and my libc.so was a linker script.=20
I'm guessing that this is the same, since DBDirect uses hs-plugins to=20
load a module which requires libz. Maybe you could try loading the HSQL=20
MySQL module into ghci and see if you get the same problem. If you do,=20
maybe you could try to remove libz from the extra-libraries list in the=20
package configuration for hsql-mysql.
